Actually, it is just the opposite.  Most high trackers get an earlier roll, so they will go with higher and/or longer pin positions to promote length.  If a bowler tracks very high, then pins above the finger line are needed to keep the track off of the fingers and/or thumb.  There are exceptions of course.  I used to track incredibly high but I still liked using low pins even though I would thump my middle finger hole.
