There is no risk of powder contamination unless there are portions of the bullet lube grooves exposed inside the case neck. That cannot happen with straight wall cases, and bottle-neck cases will only allow that when the seated bullet is significantly below the case neck.
Also, after application the white lithium grease becomes tacky from exposure to the air, so there is little chance of grease transferring to the powder.
