Warsaw Station Clan Impersonation

I’m embarrassed to say it, but the following question has become super relevant to a couple of decks I made recently:

If you tap Warsaw Station as a Nosferatu declares a Clan Impersonation to another clan, does the acting vampire unlock from Warsaw when successful?

Note “the acting Nosferatu untaps" text in Warsaw.

Thanks,

Warsaw Station
Nosferatu, 2 pool
Master: unique location.
You may tap this card when a Nosferatu announces an undirected action. If that action is successful, the acting Nosferatu untaps. You may burn this card (even if it is tapped) to move a Nosferatu in torpor to the ready region.

Clan Impersonation
2 blood
+1 stealth action.
Choose a clan and put this card on the acting vampire. This vampire is considered to be of the chosen clan instead of his or her original clan (if any). This vampire can burn this card as an action.

Hoping that maybe you can untap as Nos from Warsaw before Clan Imp makes you not a Nos...

Per the detailed play summary, the action becomes successful before the action resolves. From this, one would infer the acting Nosferatu unlocks before the clan is changed. Is the detailed play summary wrong? Or does the card text need to be updated to clarify “untaps after resolution”?
