It does; from the switch spec:

====
Case expressions must all evaluate to distinct values. Const or
immutable variables must all have different names. If they share a
value, the first case statement with that value gets control. There may
not be two or more default statements.
====

Which seems sensible and should apply to the runtime evaluated case
statements as well if that gets added.

Haven't tested that though to see if that is actually what happens.
