Great Googly Moogly!
That's the sealiest thing I've ever heard!
I'm too lazy to check if the RRG has anything to say about "and", but it would be pointless to not move - Disengage is NOT Evade.
Since the enemies don't get exhausted (like they would from a proper Evade) they'd just immediately reengage you.
The relevant rule is under "Effect":
Once initiated, players must resolve as much of each aspect of the effect as they are able, unless the effect uses the word "may."
