I believe what you are seeing here is that there is only a bold font.  
Based on a web search, Aachen Std comes in a Medium and Bold variant.  
As there isn't a standalone "regular" version, it could make sense for 
the bold and regular styles to map to the same font.

I agree that font matching is confusing at times.  Sometimes you can get 
away with partial names and get the right match, other times you get an 
unexpected fallback.  fc-match can help when testing this, but otherwise 
it seems like you are best including as complete a font name as 
possible.

In fact, if you had installed the other EB Garamond fonts, then there 
could be confusion between EB Garamond 08 and EB Garamond 12.  Based on 
the original list you provided, omitting the number would seem to be 
allowed and it would use 08.  But I'm curious what output you'd get if 
you had both 08 and 12 installed.
