No need to nitpick. Being one among many in an X, one can perfectly use "our X", "my X" and "your X" to denote the same X, there is no logical error in that.

Now, the connotation is different: saying "our X will be judged by.." spreads the responsibility among everyone and makes it too easy to shift the blame onto the next guy, while saying "your X will be judged by.." stresses on your personal contribution to the X, making it not that easy to shy away.
