It should not be. If expand the syntactic sugar what you have is

(case (quote quote) ((quote lambda) 1) (otherwise 2))

and I think it's now clear what the answer is: because QUOTE is EQL to
QUOTE, so the first clause matches. The mistake you've made is to
assume that the keys in a CASE clause are evaluated and therefore need
quoted: they're not (and in fact, you've not been quite consistent,
since you didn't quote OTHERWISE...).
