The reason that ROH star Adam Cole was able to appear at Friday’s PWG All Star Weekend Night One event is because of the new agreement between ROH and PWG.
The two promotions have agreed to a talent agreement. That agreement allows contracted ROH talents to be able to appear on PWG events. Before this deal was made, no exclusive contracted ROH talents could appear on PWG events.
It should be noted that TNA wrestlers Davey Richards and Eddie Edwards also appeared on the PWG show.
