They taped on May 1st that Dog Collar match, then had a talent meeting early on May 2 where they told the talent about the ban, then had the big next taping round afterwards, where WWE talent was involved.
So... we don't know if WWE eyes were around when that Dog Collar Match went down or if they heard about it at some point between it ended and that talent meeting happened and were actively involved in the decision, or if TNA made this decision on their own when they realized that a match like this might anger their Daddy.
Giving their track record and how WWE usually acts and the way this partnership has been going so far (and how it at least seems to evolve into) it's definitely not far-fetched to think they were in some way part of this decision. Be it actively or passively.
