Problem

On the below screenshot, In segment 84, users User 2 and User 3 have added both comments and corrections. User 1 (current user) user color is orange, User 2's is yellow and User 3's is light blue,

In the comment section on the left, current user sees one of own comments highlighted in orange for a different segment. The comments for segment 84 are both displayed in gray. Therefore, it's impossible to distinguish which comments are from whom.

Solution

The comments in the comment section should be color-coded so that individual users can be distinguished from one another - just as the track changes of individual users have different colors. First the creator of a comment should be used for the color and as soon as somebody answers to the comment, the latest responding user should be used for the color.
