It doesn't mean you 'shouldn't' divert if the weather drops below minima and you have enough gas on to consider other options. Of course you keep updating the weather to keep an eye on what is happening.
I'm not sure if I understand it right. So, like you said, in the event of an emergency we must divert anyway, so why do we have to check the weather after the EEP even if it is lower than the minima?
