That's not what it does, no.  The loop in font_find_for_lface limits the 
number of fonts that are considered to some foundry, family, registry and 
additional style, and only considers more fonts if no suitable fonts have 
been found.

That's the purpose of the loop at the end of font_find_for_lface.  It 
starts with a specific spec and gradually makes it less specific if 
necessary (that is, if no suitable font has been found with a more 
specific spec).
