If you read our documentation, found at https://confluence.atlassian.com/display/STASH/Using+pull+requests+in+Stash you will read:
Participants can commit new changes to the branch. Stash auto-updates the Commits tab of the pull request, so you can see exactly which commits will be merged. Stash is smart about comments, moving them along when lines are added or removed. If a line with a comment gets removed, you can still view the comment in the activity, but Stash marks the diff as outdated to let you know that this piece of code has been changed in recent commits.
I would encourage you to continue reading through the Stash documentation, or better yet, play around in the product (you can trial it for free!).
