Yes Rune,
You described exactly what I meant. This gives a very high flexibility and also allow to combine a reverb with multi tap or other delay based effects for various advanced space effects extremally usefull on some tracks (leading guitar, vocal etc).
You are right that in that cases the delay can be before or after the reverb but I would use a delay as first just for logical reasons. The only case when this makes a difference is when you use modulated delays (choruses, flangers and others).
Regards,
