Would you believe that I must have asked that dozens of times over the years --- and as far as I can recall, that's the first time it's ever received a correct answer, from people with a technical background included?
How depressing. I'd assumed your reason for describing it as "a claim I fear I may have made previously" was that you took it as obvious that everyone here would have no trouble with it. (My answer would differ from Gene's only in that I'd have added that we think of what a mirror does as exchanging left with right because the things we look at in mirrors -- most notably ourselves, but plenty else besides -- are much nearer to being left-right symmetrical than to being top-bottom symmetrical.)
It's an excellent example of how a badly-formulated linguistic trope may confuse its users so badly that they become incapable of disentangling its distinct meanings, even after those are explicitly pointed out. WFL
Yes. Though it's not only the linguistic trope that's at fault. (There's a *reason* why people commonly think that mirrors swap left and right, which is logically prior to that trope.) -- g
