I experimented earlier today with this case a tiny bit and
couldn't find any obvious breakdowns. It also refreshed my
memory that \relative pertains to the *first* (not necessarily
the highest or lowest) pitch in the chord, and single notes
following a chord in a relative expression also follow the
*first* note of the chord. See test example attached.
To address your exact question, I would understand David's
proposal to mean that the first *pitch* inside the music
expression would be taken as the reference pitch. Subsequent
*pitches* are relative to the reference pitch.
\relative { <c' e' g'> <c e g> }
would mean the same as:
\relative c' { <c e' g'> <c e g> }
Both triads start on middle C, but the first is spread more than
two octaves, while the second is all in one octave.

No change. q works by repeating the pitches, not by "replaying"
the input syntax. Otherwise even the current behaviour of:
\relative c { <c' e g> q q q }
would engrave each q an octave higher than the one before.
