Having taken a few apart, I very much doubt that.  I think they try 
to get the phase center coincident with the mechanical center, but 
knowing that it won't be exact, they want you to orient it so that 
the residual error is always in the same direction.  You can point 
the arrow in any direction you want, as long as you do it consistently.

Best regards,
