TOPIC: Joomla Article separator between readmore/Comments

I add the onAfterDisplayContent::JOSCusereturn to place the comments button after the readmore button, it work...
But the Article Separator is now between the readmore button and Comment button. I really like to place the article separator after the 2 buttons, not in the middle...

Is there an easy way to do that?
