Why are women heroes always facing the wrong direction in fights

Unfortunately for Wonder Woman and Black Canary, the fight happened in the opposite direction that Batman told them it would be.  Wonder Woman turned around fast enough to not flash the enemy her butt, but Black Canary wasn't so lucky.

At least they didn't get captured this time like earlier in the same run.
