According to 'greybot' from #bash on Freenode:

> foo && bar || baz is not equivalent to 'if foo; then bar; else baz; fi'.
In the former case, baz will happen if *either* foo *or* bar return false.
In the latter case, baz will only trigger if foo returns false, regardless
of the exit code for bar. See http://mywiki.wooledge.org/BashPitfalls
