Sounds legit, though she could've possibly gone into detail on incomplete, and co-dominance, which could actually explain situations like lava and plant bending instead of "Well he's got a 50/50 chance of being either" which is unscientific since you'd have to propose a mechanism as to which element the kid can actually bend. Someone who's a fire bender, but has their fire bending gene suppressing an earth bending gene would have an easier time lava bending once they master fire bending. The swamp water benders, then, could be water bender who's water bending genes are suppressing an earth bending gene.
Also, Biology tends to dislike leaving things as chance, it just happens, or it doesn't. A simple mechanic like the mother's chromosome being selected for in comparison to the father's could potentially be in place to solve that, acting as a second veto since the spirituality gene obviously doesn't account for it. For example, if the mother's a water bender, and the father's a fire bender, the mother's bending chromosome would act as a veto against the father's bending chromosome (just like whatshisname). It's not that weird in biology either, genetically speaking, females have the upper hand on multiple factors.
What's more is the child's innate personality could come into play with breaking such a veto (It's been explained time and time again there's a direct influence between a person's ability to bend and their personality.) For example, someone with WWeeFFaass with the "personality" of a water bender would be a water bender since their personality would make it more adaptive if they were to bend water (that shit tends to happen in nature). Where it would get confusing is if someone with WWeeFFaass has the personality of an air or earth bender. We'd have to look at the circle to see which element veto's the other. An earthbending personality with that genotype would be a water bender if their genes are more dominant over personality, or a fire bender if their personality has more dominance over their genotype. That could easily be figured out with a simple population study. Someone with WWEEFFAAss would be easy, it's based on their personality since it would fit neatly with one of the elements. As for the fluidity of personality, it's all a matter of which element their personality more closely fits since no one is 100% one element, but that can also be said about 50% one personality, and 50% another.
Plus, a person's environment could definitely shift that into a certain direction. Given that much of our subconscious personality is defined well before we could even think for ourselves (and thus, bend) with how our parents treat us post birth, someone with WWeeFFaass born in the water tribe would end up with the innate personality of a water bender.

The methods Iroh displayed in channeling lightning-bending attacks away from one's heart were for bolts that would have normally killed a person. The electrocuters in Korra aren't using that powerful a charge. They're just stunning people. People probably could channel the current away and be unaffected by it, but they were all caught off-guard, so it wouldn't have helped a bit.

The firebenders in Iroh's time would also lightning bend during duels all the time, and given that lightning comes out at the speed of electricity those benders were dodging with unreasonably magical reaction times, which takes the mental reflexes that could easily deal with a stun gun. The issue is more with the lack of formal bending training. I guarantee that if the equalists tried to stun Azula, more times than not they'd end up with a taste of their own lightning...and then some.
