I think the problem here is is the order of operations in which things are
executed.
In this case, I think the maya module is being imported before
userSetup.py/mel are run. So, even though you change the path before pymel
is run, it's already "too late" to affect where maya is imported from; so
when pymel runs, and checks the maya module, it finds the wrong one.
The .pth file works because it's a standard python way of modifying the
path, and so essentially happens as soon as python starts up, before any
special maya python magic happens.
