After squeezing, the entire envelope of the tendon sheath cyst remains, and the cyst can recur as long as the ankle joint is stimulated by more activity.

The main purpose is to remove the membrane around the tendon sheath cyst to avoid recurrence as much as possible, which is a much better treatment than simply squeezing it.
