BPMN2 — Complex gateway merging rule in choreography too restrictive

The rule fo merging complex gateway in choreography is

"In order to enforce the synchronizing merge of the Gateway, the
senders or receivers Choreography Activities preceding the Gateway
need to be the same Participant. This ensures that the merge can be
enforced."

but if the sender of the activity after the gateway participates in the
activties before the gateway, and has access to the complex decision
data, then it has everything needed to perform the synchronization.

The quote in the issue is from the inclusive gateway, rather than the
complex merge.
In the Choreography chapter, in section Gateways, subsection Inclusive
Gateway, under the third paragraph, first bullet, second subbullet (the
one beginning "Merge:"), in the sentence immediately after the colon
(the one beginning "In order to enforce"), replace the portion of the
sentence after the comma with:
the sender of the Choreography Activity after the Gateway must
participate in the Choreography Activities immediately preceding the
gateway.
In the Choreography chapter, in section Gateways, subsection Inclusive
Gateway, in the paragraph just above the first figure, third sentence,
replace the portion of the sentence after the comma with:
the initiator of Choreography Activities immediately following the
Gateway participates in the Choreography Activities immediately
preceding the Gateway.
