Is it a mistake, on page 4 of the linked datasheet, that "SemiBold" is shown for two different weights? I can't help but think that something like "DemiBold" was what the lighter weight was supposed to be labeled.

Yes, that's a typo. Need to redo the entire datasheet and possibly find a way to automate it using reportlab or some other PDF library. Right now, it is in InDesign and it is a pain to keep updating it.
