Maybe because the "return" of the Sphere*() macro are nothing.
The sphere get added to the scene, but I'm afraid not in the array. (as
sphere is not an expression)

As you want to store object in the array, maybe (untested) something like
#macro Sphere1()
#local Obj=sphere{<1,1,0>,1   pigment{rgb<1,0,0>}};
Obj
#end

Caveat: #local vs #declare, there might be a scope issue in previous
version of povray. (referencing a released identifier)
