Drunk Hilt is funny.
Also, testing that now.
EDIT: Tested several times on NPC; multiple ledges used (two central edges, left canal "house" edge).
P1 Olimar (test subject), P2 Sheik (edge hogger), P3 Bowser (hurtbox, generally placed directly under/near Olimar)
Step 1: Start tether with Olimar
Step 2: Sheik edgehogs after pikmin pull in (Frame 6+)
Step 3: Tether homes in on ledge, fails to catch on, remains out until contact with ground is made; special falling animation autocancels on contact with ground
Tested across a range of frames and distances, unable to reproduce the "extended hitbox" scenario.
I'll test a bit more when it isn't 6 A.M.
EDIT 2: By the way, Hilt, how would that explain the fact that the purple completely disappeared after the tether was used? Am I just colorblind?
