Clarification of the KMTV GPS-30/LOC-30 Approaches??

A couple of clarifications, please, for the IFR-challenged...

1. Is there a good reason for the holding point for the GPS approach to 30,
to be back 11.8 miles back from the holding point for the LOC approach?
They have established UBWAY right at the marker, so why do they not let the
GPS approaches use it as the hold point as well, instead of sending them all
the way back???

2. What is the controller's expectation (and/or the SOP) for getting into
the LOC approach from a high hold (like 4-5-6 thsnd) over BALES?? My
presumption would be that he expects a descent to 2600 still within the
racetrack?? Once at 2600 (lets say you get to 2600 on the outbound leg) are
you expected to complete the whole racetrack for the last time... or do you
just cut it short, cross BALES, and begin the descent???
