I believe you got this right, however, I too have no idea how SBR really
works. All I know for my part is that it's one of the mothers of all
patented technologies and that it sounds often too "artificial" for my
ears.

However...

... there's something I can be helpful with. :) The term "artifact" is
well defined and explained (at least when used near Ogg Vorbis). It's in
the first link on http://www.xiph.org/ogg/vorbis/docs.html - read
"Fidelity measurement and terminology discussion"
(http://www.xiph.org/ogg/vorbis/doc/vorbis-fidelity.html).
