Perhaps, yosito meant what the purpose of the whole command was, rather than what <() meant. It looks like a diff of diffs and commit info, but I've never used branch@{n} before. Looking into gitrevisions(7), it gives the nth prior value of branch, so doing a regular commit would be represented as an addition of a commit and its changes and doing a `git reset @~` in that branch would be shown as a deletion. Doing a `git commit --amend` appears as a modification of that commit. It seems useful.
