You're just preventing the pin from springing back and forth with the string excursion. When you do this and the beat stops, you immediately and non destructively know isn't rusty strings, capo hardness or shaping, bridge pins not seated at the bottom of the hole, a kink in the wire, twist in the wire, string leveling, coils, duplex scales, evil spirits, or any of the sundry unlikely things people guess without evidence MUST be what needs fixed. Ok, it might be evil spirits after all, but it's most likely just a bridge pin that's too loose at the cap surface and, allowed to flagpole because the string isn't resting on the notch edge at the pin because the notch edge is crushed - by cyclic dimensional change from humidity swings, string seating by techs, or both.
