Yeah, OK, it did say that. But the reasoning behind this rather complex scenario (i.e., the process) is left up to us to figure out.
"The thing came in here, sucked out all the juice, and then left a while later leaving just the crust behind, like an old chewed out tennis ball."
So, PBH eats the liquid core, leaving tennis ball(TB), then TB (with PBH still inside) has close approach to another more massive object (bowling ball?) which sends PBH and TB off in separate trajectories?
