Here's another site which addresses this subject:
http://www.vanwalree.com/optics/misconceptions.html
It states "In particular when the object distance is not small compared with
the hyperfocal distance, a short-focus lens will irrefutably offer more DOF
than a long-focus lens - at the same F-number and image magnification." So
according to this a shorter focal length can offer more DOF at the same
magnification.
