Yes I hear it a lot..."Delta XXX, are you ready for an immediate?" If no, he's told to hold short. If yes, he'd probably get the takeoff clearance right there. Or he might be told to "line up and wait, be ready to go right out". But like you said Hollis, no harm came from it. I also noticed that the tower didn't say anything else to the ANA flight until they were told to contact departure. Not that this really means anything, it's just another observation...
