PowerHA 7.1.3 tiebreaker disk with PowerPath 6.1

Client has PowerHA 7.1.3 installations with PowerPath 6.1. He would like to use tiebreaker disk as split/merge policy.
EMC has introduced PR_exclusive reservation in PowerPath 6.1 and EMC support says:
"Support for PR_exclusive reserve_policy on EMC hdiskpower devices: This support allows hdiskpower devices to set Tiebreaker disk in PowerHA."
Moreover EMC official documentation confirms that PP 6.1 introduced PR_exclusive and it's supported with PowerHA tiebreaker disk: page 356.

Nevertheless IBM support confirms in 25630,820,820 PMR that tiebreaker is NOT supported with any PowerPath version.
