Oh cool but what's 'HEAD^'

Carats and tildes are relative commit markers in Git. They both mean "parent" but in a different way.

Most commonly used, they are the same. HEAD^1 (or HEAD^ for short) is the same as HEAD1 (HEAD). Always.

The difference comes when they stack. So HEAD^2 means "The second parent of HEAD". This only means anything if there's been a merge. In a merge, the main branch is parent #1; the merged in branch is parent 2. So, HEAD^2 will be the merged parent, whereas HEAD^1 will be the parent merged into.
