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.
