Well, we shouldn't expect it otherwise, since...

>   #declare Scale = 2;

..... this loop...

>   #while ( Scale >= 0.25 )
>

..... is terminated here, without altering Scale from its initial value 2:
it'll never drop below 0.25, so making the execution everlasting.

I think they should try this instead:

blob {
  threshold 0.5
  #declare Length = 0;
  #while ( Length >= -30 )
    #declare Scale = 2;
    #while ( Scale >= 0.25 )
      sphere { <0,0,0>, 20, 1 scale <1,1,0.9>
        translate <Length,0,0>
        scale Scale
      }
      #declare Scale = Scale - 0.1;
    #end
   #declare Length = Length - 0.25;
  #end
}
