Yes, even if you are successful in pushing the roll you still end up with a condtiion. What condition is an RP decision between the player(s) and GM. And after pushing the roll you could end up Broken.
Also, it's possible to end up with 2 conditions after pushing a roll. One for pushing and if the trouble (I keep saying challenge) dictated you received a condition on failure of the reroll.
Edit: I was mistaken, you can push a successful roll as well to get more successes. Page 71 in the PDF (69 in the printed book).
