Very confusing, yes?  The form prompt text should be changed so it correctly describes the actual feature instead of a deprecated feature.

The file size of the PDF would also be smaller because you are embedding only part of a font. When you subset a font, you usually just embed the characters you are using (obviously it depends on how you are subsetting your font). That's why somebody on another computer would have to have your same font in order to make changes.

A detail I found in my experiments with subsetting in Scribus is that if you view the PDF font properties, say in Acrobat Reader, you won't see the real font names.  So any person who receives your PDF won't know what the fonts are.  Adobe InDesign subsets fonts with the correct names in the PDF, for example "Eurostile-Condensed (Embedded Subset)", whereas Scribus subsets fonts with generic names in the PDF, "Fo0S0" in the same example.  It's for this reason that I don't subset (at least until Scribus exports font data correctly).
