Yes, the timing is different, at least the way I know them (though as you found, you can move from one to the other). I'd doubt the way I play them would be identical in other ways but I think they are close enough to be thought of as the same tune (and in this case, we do know a traditional melody was used for the chorus).
I'll pose a question to you:
Is Red House (which I think is in Playford)
