Sure, call it "short-circuiting", my comment stays the same:
in which way is it related to *associativity*?
In terms of semantics, all three (++), (||), and (&&) are associative
AFAICT, so the choice of which associativity to use in the syntax is not
related to the semantics (instead it's likely related to secondary
concerns like efficiency).
