Because that's not what binding means (have a look at the CLHS glossary).
Ok, but then the question only becomes, why do we have "multiple-value-bind" rather than something like "multiple-value-setf". But with the solution you provided, I can see that question is stupid.
The less ugly way to write this is:
(setf (values (slot-a x) (slot-b x)) (some-function-that-returns-two-values))
Nice! My mind has not yet been warped enough to the Lisp way so that I could think of this by myself. I find this beautiful. Thank you!
