No. It is preferred that Reviewers create replies to their comments to clarify them. 

One of the many advantages of Review My Elearning is that it creates a record of the comments and conversations. This documentation can be used later by teams. 

Also if a comment is edited it could create confusion and more work. 

For example consider this scenario: 

• A Reviewer creates a comment requesting that fonts be changed to blue.
  
• The Developers see the comment and begin work. 
  
• The Reviewer changes their mind, edits the comment to say 'green'.
  

The developers would want a record of the change in that case. So it is better that Reviewer creates a Reply to their own comment to clarify the change.
