But timelocks come with some disadvantages, this is why we will use Asymmetric revocable commitments. In our example Irene and Hitesh exchange Bitcoin.

Instead of creating a commitment tx signed by both parties, they will each create an asymmetric commitment tx. The commitment tx of Hitesh has a 5 BTC output to Irene and a 5 BTC output to Hitesh with a timelock of 1000 blocks. And Irene has the opposite tx. They both exchange the transaction and sign it. If someone broadcasts it he will pay the other immediately but will need to wait for 1000 blocks for his payment.
