Missed it By THAT Much

Article in New Scientist:

"...when Cassini's radar tracked surface features on the moon, scientists found evidence that Titan rocks slightly due to tiny shifts in its rotation rate. Currently, Titan spins an extra 0.36° over the course of a year beyond what it would if it were in perfect sync with the moon. The moon's rotation rate also appears to be slowly increasing."

That is approximately sixteen kilometers that the base of the ribbon would need to move each year.

Hyperion, the moon that the ribbon may need to periodically dodge, is three hundred and sixty kilometers in its longest dimension.
