how to use release branch to increment version using setuptools_scm?

I am looking at https://github.com/pypa/setuptools_scm

and I read this part https://github.com/pypa/setuptools_scm#version-number-construction

and i quote

Semantic versioning for projects with release branches. The same as guess-next-dev (incrementing the pre-release or micro segment) if on a release branch: a branch whose name (ignoring namespace) parses as a version that matches the most recent tag up to the minor segment. Otherwise if on a non-release branch, increments the minor segment and sets the micro segment to zero, then appends .devN.

How does this work?

Assuming my setup is at this commit https://github.com/simkimsia/test-setup-py/commit/5ebab14b16b63090ad0554ad8f9a77a28b047323

and the same repo, how do i increment the version by branching?
