I reasoned that they represent two different ways of explaining, where one might fit some people and the other might fit others. I felt that merging them both into the same answer would disturb their respective clarity (if there is any ;-) .
I think they would be a more complete answer together - the risk when keeping them separate is that one gets voted up and the other is effectively hidden by other answers.
You could always have your main answer, then a 'technical appendix' which the reader could peruse if they wanted that extra information.
That said - I don't think there is anything wrong with posting two answers in any case. I think they are both good.
