What are these branches on bitbucket?

Question

Bitbucket

Who will tell?
These are not new branches. The branch is always the same - master.
There are no problems with this, I'm just wondering what it is and how to do it
so that this doesn't happen.

Answer 1

If there is only one branch, and two people worked in it, then these are simple commits without a rebase. When you pick up changes to push your own - do a rebase - and this will not happen.

Answer 2

Look at the comments for what it is. But if these are not branches, then pull requests are possible
