Thematically, this could be seen as Abram performing a longer ritual, with the sharpness increasing over time. And if he's interrupted mid-ritual, his sword is still sharp, but not at maximum sharpness. I guess you could then wonder how come some bits of the ritual take as long as it takes for a dude to walk from home to the town square, while others take as long as a trip to some out-of-town location, but that bit of weirdness applies to all Noon actions, and a bunch of the Shootout ones as well.
Mechanically, I think limiting spells to one per dude would be too restrictive, since spells already have a limit on which dudes they can attach to.
Regarding the video, I can see how that's annoying timing, hope it hasn't set you back too much.
