I'm not sure if i haven't missed something, but to your realize that in
this case the offset isn't applied on top of the override (as the
comment suggests), but replaces it?  This is self-evident in the example
below:

\relative c' {
  % default
  <c e g b>1\arpeggio

  \override Arpeggio.positions = #'(-5 . 5)
  <c e g b>1\arpeggio

  \offset #'positions #'(-1 . 2) Arpeggio
  <c e g b>1\arpeggio
}

with current master (a82d8622e6b1be36169de7d2fe1f9aa88618933b,
containing offset patch) the last arpeggio is shorter than the second,
while it should be longer in both directions.

best,
Janek
