My gut feeling is:
Yes, there is a distinction between game end glitches that interact with the game's intended gameplay in some way first, and ones that don't even carry a pretense of caring about the game itself.
To that end, we might ask what existing TASes might be included in this new categorization.
The first one I thought of is Pokemon gen 1 save glitch (
http://tasvideos.org/2687M.html ) but even that interacts with the gameplay in a small way (re-arranging inventory and such).
A2600 Superman pause glitch (
http://tasvideos.org/2226M.html ) is a pretty good candidate. It basically engages in nothing that looks like gameplay.
Wizardry V save glitch (
http://tasvideos.org/3470M.html ) is another good candidate - corrupting save file and declaring the game beaten.
Of course, it's unclear how much gameplay can be involved before it can be considered to engage with the gameplay - all of these other TASes interact with gameplay in a very minor way to set up their glitches or to win after doing so. This is the first one, as far as I can tell, that does not bother at all with gameplay. So perhaps it is in a category of its own after all.
