variable binding fails with :or guard

Question

The following works
fine:

(match (link: 'F) (link: ('F :as x)) x) ;; => F

But fails when I try to use an :or guard:

(match (link: 'F) (link: ((:or 'F 'T) :as x)) x) ;; CompilerException java.lang.RuntimeException: Unable to resolve symbol: x in this context
