you are correct -- the last two modifiers are appositives.
i'm not really sure what you mean by "reasoning", as you appear to have already identified what's going on.
the only thing that i think you might be asking about is the
order of the appositives -- is that what you're asking about?
if so, then that's pretty random -- those are just two appositives, for which the directions are basically the same (put them after the noun "antipodes"). since you obviously can't put both of them immediately after the noun -- you have to put one after the other -- they've chosen the phrasing in which the
shorter of the two appositives is used
first, in order to make the sentence more easily readable.
as an analogy, see the orange and blue examples in the following link. it's not an exact analogy, since they aren't appositives, but it's the same sort of deal (the order of 2 constructions is dependent on their relative length):
