The text on purge states that it "discard all enemy cards..." however it does not remove enemy handicap cards or hybrid handicap/x cards.
Thanks for the link but i don't think that thread addresses the issue with Purge not removing all enemy cards as it states in the card text. The only mention of the card is that it was updated to also remove friendly handicaps as far as I can see.
