It's also an promotional card for the app. So not really a new type of card, and not really that strange that it looks like an card from the app.
from the description on BGG wrote:
Promotional ally card that usable with any Pathfinder Adventure Card Game set. In addition, it has a code printed on it that can be redeemed for the same card in the Pathfinder Adventures video game.
Edit: Oh, and it's sendt out to both subscribers that get the base set and/or the Character Add on.
