G's connection to truth is that for EVERY natural number that you could ever try, NONE of them will satisfy that relationship. In F there is no "short cut" to use induction on, so the semantic link is infinite in length, and thus its "value" would be infinite, which is not a natural number, so doesn't break the definition. You don't seem to understand that infinite chains make something true but not provable, likely because you are just ignorant of how infinity works. That would also explain you other problems with logic, as most of those boil down to not understanding operation that work over a countable infinite set.
