Looked like a goddamn hard dock to me, given those nasty furrows (some part of my head thinks the ships should have vaporized on impact or just bounced apart rather than gouging in.) But I'm not masochist enough to put the dvd in again to look, so I'll let it go on default.
Let me put it this way: take two pieces of aluminum foil. Fold them so that each has a pair of edges that vaguely look like the starship edges. Crash them together however you like.
Hold the pair up by the edges of one of these crumpled pieces. Do you want to suggest that it's not possible to pull your held piece away fast enough that the other isn't left behind?
Not to be too picky (or deliberately obtuse ... HONEST!), but I don't think you can get interpenetration with these pieces of foil no matter how you fold them or smash them. We're talking superstructure gouging its way through decking, objects of various tensile strengths, some that may contract or expand depending on the heat of impact or the cold of space or the you-fill-in-the-blank properties of the colored space they are in.
After the collision, I didn't even think of it as enterprise and scimitar, it was more like BRUNDLEFLY or ScimiPrise, a whole new form. The idea you could achieve an extraction so simply just hasn't ever registered for me.
