I spend most of my playing time below the 12th fret, especially when playing chords. My time above the 12th is single notes or double stops, and often with vibrato or a bend. Since most of the chordal stuff is below the 12th fret, would it make sense to intonate on, say, the 9th fret? Would this bring the chords on the lower portion of the neck more in tune? Or, do I completely misunderstand how intonation works?
