In addition, there is "a over b" which does not have such a stroke (but normally parenthesizes). So one might have a character telling that two parts should be grouped over each other.

But in a notation like UTN#28 you would always employ parens. The layout
would drop superfluous parens (in the first case). Hence, the
distinction becomes presentational again. With parens, you get the
proper inline equivalent,
Remember, using semantic markup means that you have the ability to do
scoping (here by overloading the parens). That makes all the difference.
