Untrue, sorry.
The rule is "a tree entry that describes a tree object sorts as if its pathname component has a trailing slash '/'". All your sample trees should satisify that rule (or the implementation of Git that created such a tree is broken).
In hindsight, if we used the collation order that puts '/' before all other bytes when sorting the index entries and the tree entries, it would have made a lot of implemenentation details clean and easier to work with, but that would have been feasible in early 2005, and not now.
