I concur, it seems low effort, and the only real common "myth" (the 1st one) is not really disproven. Infact the very example he puts goes to prove it, as it is going to become an infinite loop given large enough N....

Also compiler optimizations should not affect the result. Specially without "fast-math/O3" (which arguably many people stupidly use nowadays, then complain).

-ffp-contract is annoying exception to that principle.
