That is just what you are seeing, it isn't what is actually happening. The tappet is moving up and then back down but you can't see it because the tools you are using aren't good enough. If you used a yard stick to measure bearing clearance you would say the clearance is zero because you wouldn't be able to see it with the yard stick.
