> This has to do with the _destination_recipient_limit parameter = 1.
As documented, this controls how Postfix DELIVERS mail, not how
Postfix RECEIVES mail.
default_destination_recipient_limit (default: 50)
The default maximal number of recipients per message delivery. This is
the default limit for delivery via the lmtp(8), pipe(8), smtp(8) and
virtual(8) delivery agents.
Setting this parameter to a value of 1 changes the meaning of the cor-
responding per-destination concurrency limit from concurrency per
domain into concurrency per recipient.

As documented, the policy delegation protocol controls how Postfix
RECEIVES mail, not how Postfix DELIVERS mail.
