That is precisely what I was describing.

I thought the same thing (although even when I am thinking I don't misspell
the word "should" :) ).  There IS absolutely no reason, whatsoever, for this
to work.  Unfortunately, in my case, it did.  That is why I wanted to know
if anyone else had witnessed such an anomaly.
