Listening to the video, I don't agree with posters that say Eva was to blame, certainly not a "rogue".
The controller made a mistake then got flustered and started mixing up what she was saying... call signs, headings, stop climb vs expedite. You can hear the other pilots detecting that, eg AC asking for confirmation on altitude. Then later she was clearing behind events: letting a subsequent departure level at 2000, switching AC to next sector while it still appeared to have a conflict with Eva, and then not fully monitoring Eva despite it all.
Eva got some rapid fire instructions that contradicted each other: the initial left turn, then as they were passing north a reversal to a right turn then back to a left turn to 270, then just "southbound". At that point they were obviously (and reasonably) confused and asked for confirmation of heading (3:08 in the youtube video) which they didn't get, just more instructions where the controller mixes up north and south.
A couple posters mentioned that the turn left to 180 instruction is not on the live atc audio. Liveatc is often unreliable, audio dropouts due to multiple frequencies monitored. The FAA spokesman quoted in the LA times did say the controller gave that left turn.
