Rebuilding after switching branches

[DsyD]

I download a branch using Git, run Setup.bat and GenerateProjectFiles.bat, then build it in VS 2017.

Now if I switch to another branch, do I need to run Setup.bat again? The sticky at the top says:

As well as downloading the dependencies matching your repository, this will register Git hooks to sync dependencies every time you checkout or merge. It’ll only download the differences needed to update your working tree up to the right state, and it can be safely interrupted or resumed at any point. It won’t clobber changes you make locally without prompting you first. This system works for any commit, not just for the snapshots of ‘latest-preview’ tagged builds that we’ve been limited to until now.

But that was from 3+ years ago. Does this still work, i.e. if I switch branches, it automagically updates whatever I would have needed from Setup.bat without having to do anything else?
