I got the impression
they were praising when the dog finished pooping - i.e. they
waited until it finished. And that's actually not great
timing - you should praise when the dog starts (although not
enough to cause him to stop, obviously).

I'm used to Bella. Even the mildest acknowledgement when she starts
pooping causes her to stop. She's a sensitive flower. She did very well
with the waiting until she was finished and then immediately praising -
and she learned to eliminate on command.

Your version is much better for most dogs.
