Not really.
It happens to hold true for @{0}, because by definition you couldn't
have been on a different branch than the current one when you made
the topmost commit on the current branch. For @{1} and higher, it
is always "where was the current branch at N commits ago?" which is
different from "where was the HEAD at N commits ago?", unless you
always use a single branch and never switch away.
