deleting git branches

[metulburr]

first i mirrored the repo in case i messed something up.

I hard reset the head back 3 commits. Copied the updated files back to the repo and created a new branch for them.

metulburr@ubuntu:~/repos/ShooterGame$ git checkout -b cleanup_after_menu
M	data/states/game.py
M	data/states/game_over.py
M	data/states/menu.py
M	data/states/options.py
M	data/tools.py
Switched to a new branch 'cleanup_after_menu'
metulburr@ubuntu:~/repos/ShooterGame$ git add .
metulburr@ubuntu:~/repos/ShooterGame$ git commit -m "cleanup after adding menu"
[cleanup_after_menu ec53c60] cleanup after adding menu

The comparison is correct as it goes to from the correct branch to the correct branch. However the old branches are still there. Its not a big deal as the comparison is correct in the last new branch, but i am wondering how these branches exist if i reset it back 3? Or is that because i never merged them into master in the first place? It also does not show in git log, but shows on the website.
