The biggest problem is that the phrasing implies that non-phantasms would be automatically saves against. This is an issue, because there are non-phantasm illusions that are still mind-effecting (patterns, mostly) and thus could sensibly affect the caster as normal. Furthermore, this is supposed to be a "rulebook" designed to clear up confusion over rules; a rule which is only causes more confusion isn't likely that helpful.
The rest are minor complaints. If you change the phrasing from 'phantasms' to 'mind-effecting illusions' then you're left with rule 38C exactly, which makes me wonder why both with rule 54A. And the title, while a silly comment, definitely should be changed to something more fitting to what the rule actually does.
