I don't know about that.  If the change is gradual enough, could the
length of the neck not just grow a few steps behind the lengthening of
the tail?  I don't imagine a difference of a couple of inches or feet
would throw the entire animal terribly off balance.
Or what of the idea that some sauropods developed different postures,
then, to help keep the center of gravity over the hips?
Err... maybe I'm going a little far with this.
