Actually no. The card reads " When ATTACKING a ship inside your auxiliary firing arc, you may add 1  critical  result."

So, you have to be attacking THAT ship FROM your AUX firing arc to be able to add the critical result and cannot add a crit result attacking from your primary arc just because someone is behind you.
