Yes, the \revert command is properly explained.


My main concern is updating this sentence (after \once we go back to
the "current" value, not the default value):

Changing the code example to have an \override in effect (red color)
would explicitly show this: after using \once we go back to (red
color), not to the context's default (black color).
In my opinion this doesn't overly complicate the manual, and might be
more clear.
