Your statement was:

"The numeric ranges 0-10 and 10-19 overlap, just as the time ranges 
00:01:00-00:00:02:00 overlaps 00:02:00-00:03:00."

I was just pointing out that is not necessarily true. As was pointed out 
upstream there are good reasons for not having 1:00-2:00 and 2:00-3:00 
overlap.

As David pointed out it is about following the documented behavior. I 
still have to remember, on occasion, that BETWEEN actually includes the 
end points not just points in between them.
