Dogged Pursuit at superior on a vampire already having one attached

If I control a vampire that has a Dogged Pursuit atteched to it. Can this vampire play Dogged Pursuit at superior to try to block another action?

What is confusing to me is that if it is played at superior there is no guarantee that it will get attached to the vampire, there is a condition for that.

Dogged Pursuit
Only usable by a locked vampire.
[ani] This vampire unlocks and attempts to block. If this vampire does not block this action, lock them after action resolution.
[ANI] As above, and if this vampire does not block this action, put this card on them after action resolution. This vampire can burn this card to get +1 intercept. A vampire can have only one Dogged Pursuit.

If you can´t block and dont have burned the old one for +1 intercept you can´t attach a second one on the vampire, if you burn the old one, and can´t block, the new one will be attached in the end of resolution
