The volume element is calling that itself whenever needed, i.e. when a
controlled property is used and it needs new values. That will then go
through the control binding and control source so a new value for the
property is known.

Yes, and you bind that one to the volume property then so that the
volume element asks your control source about the property value at any
time.
