You *should* be able to do something along the lines of what he's trying.
Here's the workaround:

Use macros!

#macro blobby1()
        sphere{x,2,1}
        sphere{y,2,1}
#end

#macro blobby2()
        sphere{-x,2,1}
#end

blob{
threshold 0.1
blobby1()
blobby2()
translate 8*z
pigment{rgb 1} finish{ambient 1}
}
