Remote points are attached to the geometry through constraints equations (CE). This defines coupling between the dofs of the remote point and the dofs of nodes of the scoped geometry. However, each node can only be coupled once : if a node of the geometry is scoped to two or more remote points, this causes overconstraint and the solver will delete one set of CE to relieve the overconstraint. Thus the warning message to inform the user. Remore points can be defined manually, but are also used internally for moments definition, point masses, and joints.
