I'm not sure who advised you of this but there is only one advantage to placing audio on a separate file. That reason is to be able to adjust the inframe or outframe amounts of the video file to adjust the offset of frames between layers.

This is an advanced technique that I have suggested to people in the past as a workaround but this is not a solution that someone should use when creating new shows.

If you must play audio with video, follow Simon's statement and render them together as one file, verifying they are synced in post before loading them to the Catalyst.
