Of course that's wrong :-(   'separate' is the wrong concept.
A composition operator 'terminates' a dwarf expression,
sort of.  

Or perhaps delineates a dwarf-expression?

Since the composition operator operates on the stack as a whole
(not some fraction)  it's not really  a block-scope terminator,
or at least not a very flexible one  (not clear to me how
a more flexible one would be meaningful so I do not see any problem
with the current definition other than the issue
Marcel Mettes brought up).
