Someone else has just been caught out by 'moving' objects when using 
scale, I was wondering if adding a non-origin sphere to the example would 
highlight this, perhaps:

Scale also alters the vector components of an object

For example

  sphere { <1,1,1>, 1
   scale 5> // Evaluates as <5,5,5> so uniformly scale
       // by 5 in every direction.
       // but also multiplies the vector location
	// resulting in a translation to <5,5,5>
  }
