Siege of Winterfell

"House Stark only.

You cannot claim power for your House except during a Military challenge.
Response: After you win a Military challenge, claim 2 power for your House."

I have been told by a fellow player that you are still allowed to satisfy the claim of a Power challenge when using this Agenda, because 'moving' power from their house to yours is not the same as 'claiming' power for your house. Is this true?

Huh, I searched the document for 'Winterfell' and it didn't find it. My apologies, sir.

It's not a specific card (Siege of Winterfell), but it is the FAQ "Is there a difference between moving power and claiming power?
