At this point, it's a virtual certainty that William Morris and / or ABC media relations are tipping photos to photo op's in order to maintain Ali's appeal.
William Morris is out testing the waters to see what Ali's professional opportunities are in the business. Keeping her in the media is part of that strategy/timing.
ABC is solidifying goodwill toward the Bachelor/ette brand by extending interest in the franchise in the week post finale, while Bach Pad is airing, before they announce the next bachelor.
The business of television explains everything.
These guys are not Robsten. They don't have paps following them. They have agents and media relations people trying to flak the couple.
That's not to be critical of the Happy Couple -- their economic future depends in part on the same thing.
The media bookings and photo op's made Tessa crazy eventually (not Andy's being stationed overseas, but rather his obsessive need to remain in the public eye, shirtless, "doing good"), but here at least, both Ali and Roberto seem happy to enjoy the attention for now.
