Reroute question. Line holder.

Awarded: Fly base to X. Layover. DH from X to base.
Reroute: Fly base to X. Layover. Fly from X to Y, DH to base. Arrive many hours later than scheduled.

Does the DH not count as “a flight segment that commences after the arrival of the last flight segment as the rotation then exists.” Wasn’t supposed to operate again at all. Feels bad and new reroute pay isn’t until august…
