What's obvious to me from looking at the video is that it is done without even looking at the hands while doing it.

All my paper tape experience (not insignificant, back in the 1968-1974 era) was in places where we either spooled the tape by hand or used tape winders, hand-cranked ones.  Because of those winders all tape was neatly wound into coils, winding from the tail end so you could feed from the outside.  I think the ones we used were sold for use with movie film, because they looked just like the one on the left in this photo:

The Flexowriter I've got is interesting because it works under the assumption that you wind tape from the head end, then unspool it from the inside of the reel.  The auxiliary paper-tape reader for the flexowriter has a neat feed spool holder designed to make this work.  Here's a photo of the feed tray that feeds the reader up off the top of the photo.  The key part is the black inverted conical pillar in the center of the free-spinning tray mounted on a swing-arm.
