Correct!
"With dialer watch, the router monitors the existence of a specified route
and if that route is not present, it initiates dialing of the backup link.
Unlike the other backup methods (such as backup interface or floating static
routes) dialer watch does not require interesting traffic to trigger the
dial. "
For best practices:
"Configure on caller router routing protocols as uninteresting in the
interesting traffic definition to prevent periodic hellos from resetting the
idle timeout. Since the router uses the interesting traffic definition ONLY
to check whether the primary link is active, consider making all IP traffic
uninteresting using the command dialer-list number protocol ip deny. With
this interesting traffic definition, the idle timeout is never reset, and
the router checks the status of the primary link at the specified interval.
"
