Nakhthorheb

I was wondering about unlock abilities, on the Toreador Alexandra's card test it days she can unlock another Toreador once during the minion phase. But on Nakhthorheb it says "During the minion phase he can unlock", but it does not specify once.
Am I correct in thinking that he can unlock as many times as he wants?

Incorrect, can only be used once because "during x, do y" applies (x = minion phase , y = Nakhthorheb can unlock).

“During X, do Y”: The “during X do Y” template is used in several cards. When this template is used, only one Y can be done per X with this card. For instance, you may move blood from your vampire to your pool with Vessel only once per unlock phase.
