The issue is he was DFd for a JW violation, not apostasy or anything. . .
If he feels that he must "fake it" and get reinstated to maintain communication with the elderly parents, this is certainly easier under these conditions than if he was discovered to be a "mentally diseased apostate". It's a lot easier to "prove" you're repentant about over-drinking, a little drug use, or even adultery. He would just have to grovel ("eat shit") for 6-12 months and play the "repentant" card. THEN, he could find a reason to start to fade.
