That's because try_files is not a mechanism to "conditionally select 
configurations"[1] like the rewrite module directives (including 
"return"), but rather a way to choose which file will be used for 
request processing.  As such, try_files checks happen right before 
actually returning the response, after various access checks and 
limits.
