Proper Positions during Time Out?

[Freddy]

The Fed Officials' Manual (2006-07), p.45, counsels the two-man crew where to stand during a time-out: at the top of the free throw circles for a 30 second timeout, and at the boxes for a 60 second timeout.
Have there been any changes to this?
An alternative some have been practicing is this: one official with the ball at the location where the ball will next be put in play (throw-in or free-throw), and the other official on the center circle nearest the table for a 30, and farthest from the table for a 60.
I see beneficial things about this alternative practice, but don't know if it's something I picked up from guys I've worked with or from summer camp.
Our state didn't send out an officials' manual beyond the years 2006-07, and maybe I've missed something new.
Can you clarify for me what the current official Fed positions are supposed to be in this situation?
