Web1. TL;DR; The circuit doesn't prevent the first register (the one connected to din) from going metastable. What it does do is reduce the probability that metastable value from propagating into the rest of the circuit. Let's start with a 1-flop synchroniser. The register will clock in the value of din and align it to the clock edge.
