I think I understand what Chong was trying to express here now.

Region-aware commands are those that act on the region if it is
active and Transient Mark mode is enabled, and on the text near
point otherwise.

This explains the concept of "region-aware" commands -- they typically
switch between acting on the stuff around point and the stuff in the
region.  Like `DEL', which deletes the region if it is active, and the
previous character if not.

So I don't think it's wrong...

No, I like the mention of the mark, which helps my understanding of what
it's saying.

I've fixed that now.
