The first dot is the phi,psi values of the residue you clicked on.

When you move the atoms, the 2 dots are the phi,psi for the residue you
clicked on (residue n) and phi,psi for residue n+1 (because that changes
too when you move the C and O atoms of the peptide)

I almost never use this tool these days. You can find out why at the
study weekend :)
