Not clear that this is true, looking at the SB wording and diagram only (and with no knowledge of the system) it refers to the 'Servo feedback link". If it is indeed inside the control loop disconnecting it could very much result in a servo runaway. That said it would also seem to be a critical path and might well have a redundant path of some sort beyond what is shown.
Hopefully someone with knowledge of the system can comment on this.
