Indeed, not required. It's just leftover confusion.

[v4-0001-Don-t-load-directories.patch (text/plain, inline)]

Subject: [PATCH v4] Don't --load directories

* lisp/startup.el (command-line-1): Only pass expanded FILENAME argument
of --load when it refers to a normal file, since `load' doesn't handle
directories (Bug #16406).
