Evaluated means executed, with all the associated side-effects, at runtime 
if the _Generic expression is executed at runtime.

All expressions - including the assignment-expressions that appear in the 
_Generic syntax - must always meet the syntactic and semantic constraints 
(for example, the constraints on valid casts).  This applies to 
unevaluated expressions inside _Generic just as it does to unevaluated 
expressions inside sizeof.
