Narrative:

I had just relieved another controller and during the briefing I was told that aircraft X was issued 9;000 feet which is the standard altitude that casta departures climb to. I was also told that aircraft X was in a vector for spacing with the casta departure in front of him; due to insufficient spacing provided by lax tower. I was vectoring aircraft X back to join the SID at the ajaye intersection. Aircraft Y was inbound to lax at 10;000 feet. I saw that aircraft and was trying to get aircraft X in front of the aircraft Y so he wouldn't be what I thought would be 1;000 feet below the super aircraft. As I was vectoring the aircraft I observed a few hits at 9;000 feet which was the expected altitude for aircraft X to be at. As I cleared aircraft X direct ajaye I noticed his altitude was 10;000 feet; climbing. I questioned aircraft X and he told me that he was cleared to 13;000 feet. He told me that he had the aircraft in sight and was continuing his climb. I coordinated the altitude with the next sector since that was not the SOP altitude. I then switched aircraft X to the next controller.I don't know. It was just a mistake by the controller during the briefing.

Title: Two reports of an aircraft that was doing what it was told to do. The error was the departing aircraft was assigned the wrong altitude and came close to traffic that was level on an arrival.
