Hi,
If you look at the schematic diagram, there is no connection between REFGND and AGND_OUT, so I wont see any issues with the diagram,
As per your comment, Op amp output is not grounded, it is connected to REF_GND of reference IC which is actually a floating node with respect to AGND_OUT.
GND symbol may look like, but its the net name matters for electrical connectivity.
Hope this clarifies and thanks for asking questions

AK
