The order of arguments and outputs in a stack diagram is a convention. All RPL related HP documents (manuals, external, internal) since the HP-28C use the right aligned order, and thus using this order simply avoids problems when reading stack diagrams from different sources.
Also all somewhat bigger projects, like RPL48, JAZZ, Java, and of course SpeedUI use the principal HP convention for stack diagrams.

But they don't stay at the same position. If a command takes four arguments and returns nothing, the elements above (or below) the 4 args are on top of the stack after the command.
