A contradiction would involve two statements, but here there is only one, that the deficit (360 - v) approaches zero as N increases without bound. That a function has a limit at a point doesn't mean that the function exists at that point. The limit of 1/x as x increases without bound is 0, but 0 isn't in the range of 1/x, nor is infinity in the domain, nor can it even be in any domain.
