No, I think it may have something to do with properly
detecting all collisions. There are a whole bunch of
special cases, where short packets have crossed in the
middle of a segment. This causes a collision at the nodes
in the center of the segment, but the nodes at the ends see
their own transmissions without interference. Possibly,
having the terminator too close to (one of) the sending
nodes might make this detection less reliable. Hmmm, but
really, anything that goes past the last tap toward the
terminator ought to just DISAPPEAR, so that the length
beyond the tap should not matter.
