I always do that, but I've found that the position the axle assumes with the bike on the floor is not exactly the same it assumes after riding for a while and passing some bumps.
If the rotor clearance is really tight, it can start to make noises after riding for a while, and sometimes it can be temporarily solved by loosening the axle and tightening it again, which means that, somehow, the axle / wheel can get slightly displaced after riding.
