Bonding subpanel to electrode

[smallfish]

A bonding jumper from the cold water pipe is run to a subpanel where this bonding jumper is connected to the terminal bar for the grounding conductors. The feeder equipment grounding conductor from the service panel is terminated to this bar as well.
The feeder neutral is isolated from this terminal in the subpanel.
Does the use of this bonding jumper dissipate fault current back to the system neutral thereby interfering with the opening of the OCPD on a fault?
If this is a violation to code, is there a section in the code that applies?
Thanks

I think you can re bond the sub panel 250.54,... as in ,..in addition to the connection at the main service equipment
