No, more like:

    git rebase -i
    # squash all the commits (e.g. in vim with ctrl-v)
    git reset HEAD^
    git add -p
    # interactively pickup the RED hunks
    git ci -m RED

The main difference to jj is that the RED commit is created later with git.

But isn't the flow nearly identical with jj, because the key part, the moving of hunks, is interactive (aka manual) anyway?
