Nexus signal starts workflow?

Reading through the Nexus documentation, one of the synchronous operations is sending a signal; the documentation for the Synchronous Operations Lifecycle says:

  1. Nexus Operation handler processes the Nexus Operation.
    i. Handler Worker gets a Nexus Task from Task Queue.
    ii. Operation handler starts a Workflow in the target cluster.

I was wondering if this was a typo, or if sending a synchronous signal through Nexus actually does start a workflow in the target cluster to deliver the signal?
