It determines where McSpadden glues the bridge. Read this page: https://www.mcspaddendulcimers.com/kb_results.asp?ID=6
As a practical matter, compensation is more of a concern when:
1. You have a short-scaled instrument (like a 23" Ginger)
2. You are playing higher up the fretboard (in the second octave)
3. You are fretting more than one string (noter/drone don't care unless the intonation is way off)
4. You have a sensitive ear and notice when strings aren't quite in tune with each other
FWIW, my Ginger was compensated for GDG. When I string her DAD the intonation's OK for me in the first octave but I notice it's off in the 2nd octave. I know someone who tunes his Ginger DAA but had her compensated for that.
If you're ordering a standard 28" McSpadden and you retune between DAD and DAA often, I wouldn't worry about it. If you tend to play drones in DAA and chords in DAD, then compensate for DAD.
I've heard enough arguments about "bridge" vs "saddle" to leave me totally confused. According to Frets.com, no wonder: http://www.frets.com/FretsPages/Musician/Guitar/Setup/Saddle/saddle01.html
