Medical IT and Protective earth

I'm currently looking at some medical containment systems (bedheads and the like) and am confused by the companies protocol of isolating the earth locally at the socket.
These are Medical IT (BS 7671 S710 + HTMs & BS EN 60601 series.


I do not understand why the socket's fixings are isolated from the panel (which would provide an earth) but the panel and sockets earths are then wired to the same point.
Surely this is removing a doubled up earth minimizing and variance across the earth path?


Or additional information, the non medical sockets and supplemental circuits are earth bonded to the panels with an separate lead going to the single earth point with the medical sockets.
