Not necessarily.  It might be forwarded, it might bounce later.

It's already known that if you are going to forward your mailbox, you want to 
get your bounces go somewhere else. The bouncing on forwarded mail are mostly 
useless to the original sender. The original sender can't do anything about 

In this situation I would considering forwarding to be a secondary act that 
has no bearing on the original mail. The message was delivered to the 
recipient. The fact that it was forwarded by the recipient's mailbox is a out 
of scope for DSNs.

Forwarding can happen before the message hits the recipient’s mailbox (sieve, 
procmail). Also, recipients may have per-user filters to /dev/null mail, before 
the MUA gets it or afterwards - most MUAs allow for blocking. Often, these are 
solutions implemented to avoid harassment or abuse and there is a significant 
security / escalation risk for the people implementing the blocks if the blocks 
are discovered.
