A flight crew was notified after the fact that they flew a CRJ700 with an incorrect MEL applied to the hpsov so that the valve was not secured closed and penalties taken. The MEL for the bleed loop was correctly applied but was not applicable to the problem.

Narrative:
MEL 36-21-06 for left bleed loop rather then MEL 36-11-02 for the prsov. Both mels state 1 pack inoperative; bleeds open [takeoff at landing performance correction] applied. I called flight operations about a huffer for the next crew; I was told we did not need one per MEL. But item #10 of 36-21-06- states cross bleed start is not used for engine start. Paragraph B section 2 states both engines started prior to taxi. I should have pushed for a better answer since something was not right. It was written wrong from maintenance.
