Potentiostat Clarification needed

The below circuit is take [from here](https://www.alphasense.com/-/media/project/oneweb/oneweb/alphasense/products/application-notes/aan_105-03_app-note_v0.pdf?revision=2de3db93-89a0-4db9-bfdb-6b2767f15d44).

May I know how this circuit maintains the Potential at Reference Electrode and Working Electrode same.

Here you can see that the working electrode is connected to IC1 and Refrence electrode to IC2.They are not in a common loop.Then how this circuit maintains same potential at working electrode and reference electrode.
