Lee, this happens when the right and notes in the last measure are tied into the next measure. Have I got that right?
Opinion only: There are times when notes are tied together from measure to measure ending a thought – and the vari should be pressed for the next measure, not interfering with the music thought. Maybe a break or a fill might fit better.
Don’t take this as Gospel, I’m just guessing.

PS, Doony is right, gotta hear it played to understand.
