BPMN21 — Apparent contradiction concerning compensation handler invocations

i) Chapter/Section 13.4.5. Page 457. It says:
“Triggering compensation for the Multi-Instance Sub-Process individually triggers compensation for all instances within the current scope. If compensation is specified via a boundary compensation handler, this boundary compensation handler also is invoked once for each instance of the Multi-Instance Sub-Process in the current scope.”

ii) Chapter/Section 13.4.5. Page 458. It says:
“In case the Activity is a multi-instance or loop, the Compensation Activity is triggered only once, too, and thus has to compensate the effects of all instances.”

COMMENTS:

It seems there is a contradiction between and (ii).

• In there are as many invocations as instances are.
• In (ii) there is only one invocation for many instances.

SUGGESTIONS:

Clarify whether there is a contradiction or not.
