Multibranch circuit


So I am trying to figure out something, and learned it is called a multibranch circuit. In my electrical panel I have a 20A breaker for the dishwasher and a 20A breaker for the Disposal, and a tie-bar connecting the two breakers. And I guess they do this to eliminate the need to run extra wires, but I was looking at this picture online, and when I follow the wires in the picture it looks like you have (2) 120V wires going to an outlet, how does this work? wouldn't that turn that outlet into 240V? In my house I have a similar set-up, one outlet under the sink, one plug for the dishwasher, and one plug for disposal, and both are 120v items, so why have two hot 120V wires going into the outlet, seems like that would double the power, normally you only have one hot wire that powers both. Thanks in advance for any info.

If they used one duplex receptacle to plug the appliances in, then they would have broke the tab connecting the two terminals on the hot side. The neutral tab would stay intact.
