Recursive alpha maps (where one picture's alpha map is set to a picture with an external alpha map) would be all fine and dandy, except for the case where the client constructs a loop. Detecting this case when setting the alpha map values would be difficult as any time an alpha map is set, the server would have to check for the looping case. Instead, a far simpler fix is to simply disallow recursive alpha maps in the rendering code, the Render spec is ambiguous in this area and allows us to to ignore the recursive case.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
