I think it's up to the person writing the lexer to define what the
available sets correspond to. The comments in this link [1] indicates
this is primarily intended to support languages embedded into other
languages (first example that comes to my mind is HTML/PHP).

OK, so we are not attempting to provide different highlighting for function names and keywords (if, for, etc.)?

If we return the list of all functions and keywords in a single list of keywords for the editor, then we'll be highlighting nearly everything on the screen in the same way.  Is that really what people want or expect?

I'm not familiar with Scintilla internals, but I'd guess that you can indeed have several class of keywords; hence you can assign different highlighting to those different classes. It would make sense to have different highlighting for real octave keywords, and function names.
