No, it's not the example but the operator description, and what it says
is
"string || non-string or non-string || string"
so it's trying to illustrate that there are two options:
string || non-string
non-string || string
but maybe it's not super-clear about that. This is much clearer in the
docs for Postgres 13, which has been heavily reformatted:
