It's never claimed to be a formal superset, just pretty close to one.
You'd have to rename any variable called "this".  There is a list of
further such issues on Stroustrup's web site and they are all pretty
minor iirc.

Of course it's idiomatically different, that's the point.  I'd also say
Forth with files and locals is idiomatically different from Forth with
blocks and stackrobatics.  I'm not exactly a C++ fan and I haven't used
it a whole lot, but in my limited experience it is improves
substantially on C.  Of course I'm not a fan of C either.
