Not 'extended' that is the entire point of my question. I'm expecting 
the '||' to be identical to a logical 'else', there is no other issue.

Demand? I seek clarification, mind, if it were agreed that my sense of 
the logic were correct I'd be happy to see it change, but issues of 
logic and code flow are rigorous and not subject to opinion.

Ok, I'm at least on guard for that sort of thing from now on.  I've more and more been using &&|| constructions in place of if/else simply because the former is more compact, but I'll be more vigilant from now on.  Braces are ignored as far as truth tests on the left of any && or ||.  I can't say I like it tho, not that that matters, a thing like this is entirely at your discretion.
