Does this method really work as replay protection? This blog post describes a method for protecting against replay attacks after any hard fork on the Bitcoin blockchain. It asumes you have BTC in a wallet and want to transfer it without risking the forked coin.

In summary it says:


Buy BTC in an exchange
Transfer BTC from exchange to your wallet
Transfer full amount including newly received BTC from wallet to another wallet


According to the author, the last transaction can't be replayed on the new chain since it is for a larger amount than what that address would have in the new chain.

Can someone confirm whether this does in fact protect from replay attacks? Would this be a valid method for any hard fork?

My concern is that somebody could replicate the first transfer (step 2) in the new chain, therefore making the second transaction (step 3) replay-able.
