For IPSP it is conditional also.

Yes, that would the "condition" in "conditional".

When more than one IPSP (ASP) is served over an SCTP association...

Because an AS is _served_ by more than one IPSP does not in itself
required the use of an RC as IPSPs serving the same AS normally have
different associations.

It is when more than one AS is served by a given SCTP association, that
RC is required (to discrimintate to which AS messages belong).

This is not the place to discuss vendor-specific implementations.
