At the final review of the casket before they left, Michael made the sign of the cross. I would suspect he is still practicing Catholicsm.
Making the sign of the cross does not make one a practicing Catholic. Michael attends regularly and enthusiastically and evangelical congregation. He calls the church's pastor his pastor. He has had him on histalk show billing him as his pastor.
Some unusual practice for a Catholic. One genuflection does not make your case.
