It clings to or plates metal surfaces - bearings, journals, rings, cylinder walls. The "clinging" is not permanent. If you do a couple of oil changes and do not continue to add MoS2, most of the material that was clinging to bearing surfaces will be gone - wears off and drains out with the oil.
On the other hand, after the initial dose of MoS2, you could (should, according to some voices) reduce the amount of MoS2 you add - perhaps 1/2 or 1/3 can of Liqui-Moly MoS2 Anti Friction. The built-up layer of MoS2 on metal surfaces will only get so thick. Beyond that, the rest of the material just stays in suspension in your oil and drains out when you change your oil. That doesn't hurt anything but you don't get much benefit either.
Another user reported a situation in which a vehicle was not used for an extended period (a year?) and the MoS2 settled in the pan. Without seeing the results, my suspicion is that only part of the material settled - that part of the MoS2 which had not yet attached to metal surfaces. MoS2 in bearing journals will not settle out or drain out. So, this idle-for-a-year vehicle may have received a significant benefit from the MoS2 when it came out of hibernation, because the motor oil had clearly drained out or evaporated from the metal surfaces.
As for the MoS2, it may be 'worn off' through use and non-replenishment. As for what settled in the pan, the user clearly got no benefit, but it's unclear why this would cause any harm. Settling in a shorter term (week, month) is a non-issue. And, how many vehicles sit idle for a whole year?
