GFWL XBL Achievement Question

[Sir Boss]

I recently got myself on Games for windows live for Dawn of War 2, using my Xbox Gamertag, on Xbox, i have been gaining achievements off-line, while gaining them online with GFWL.
my question is:
what happens when i go back on-line on the Xbox, do i get both sets of achievements, or does the Xbox set revert to the last time i was online with it, what happens?

and yes, i am that vain.

PC games and 360 games are treated as different games entirely. You'll simply have 2 sets of achievements
