What if he starts questioning your actions instead of your faith and shows you videos projected on a cloud of you touching yourself while sniffing a pair of dirty panties? Do you think he would believe that was ok or would he send you to hell?
I believe the reasoning is such that, as long as you weren't hurting anyone and had lived as a 'good' person, his religious laws about not masturbating etc. wouldn't apply because, as had been understood by him, he'd done a pretty shitty job in making it clear what 'He' wanted and who he was. 'He' isn't exactly unambiguous when it comes to 'Holy' texts'n'shit(tm).
