I don't know what you mean and I stand by what I wrote. What does
"that" refer to?

I'm also baffled by the current discussion that U(r) is NOT defined
as the negative of the work done by a conservative force in going
from the reference separation to separation r (vector). Somebody
please explain why not in plain English or with a simple example,
because that's certainly what I thought the definition is.
