This is normally a result of busted user login files.
You will probably find that ssh _is_ setting $DISPLAY correctly on machine B,
but that the login process (or another shell startup file) is junking that settng.
For example, does this:
ssh B 'echo $DISPLAY'
say A:0.0 or B:10.0 ?
Every so often I run across a user whose startup files believe they
"know" the user's display and say something like this:
DISPLAY=$REMOTEHOST:0
export DISPLAY
or
DISPLAY=`hostname`0
export DISPLAY
somewhere. Which of course they have no business doing.
It is possible tht the sysadmin of machine B has inserted a similar
foolishness into the global login file (eg in /etc/profile or something).
The above scenario would be my first suspicion.

That said, I'm inclined to agree that that's not necessarily a good
idea. I always wanted to write a little program that would pop up a
Mac window to ask ``I'm going to amputate a limb at random from you
now.'' to see how many people would instinctively click "OK".
