The video clearly shows a hally hitting, unequipping very briefly around 1 or 2 seconds, re-equipping for another shot.
The comments that follow are....
h0tsex0r: What UO emulator is this? I have not seen a Double-Hally hit in 10 years!!
raklain: The Double Hally shot..
impressive, I didn't espect to see it on a youtube video
A second article about the double hit bug that was WRITTEN in October 2000 well past the UOR publish...
I agreed not to use magic on him, so (while running around and dodging his gay blade) I tell him that I am sticking to what I agreed to, that I can't use magic on him, but I will on myself. He says something like "u will die anyway" and the fight is on. I put on reactive armor and put my hally on, timing it just right. <CRACK - CRACK> The dipshit almost dies from a carefully planned doublehit, and bolts for town and safety.

The theory behind "insta hit refreshes" and the "double hit bug" could very well be one in the same...
Not one but two sources that CLEARLY shows that the double hit bug existed WELL past your date of 2.26.99 Cortez.
