Skimming the referenced PDF, it discusses the optical mouse peripheral, not the onscreen pointer. (There is one illustration of an onscreen pointer in the classic tilted-arrow form, but as an example of something already extant.)
The alleged "turn it 45 degrees, making it easy to see" rationale is only in surrounding modern text (at these blog posts and the StackExchange answer). It might be right, but if so, it's not supported in the linked 1981 document.

From ArsTechnica's article. Though it doesn't say WHY either. http://arstechnica.com/features/2005/05/gui/3/ http://arstechnica.com/features/2005/05/gui/3/
