Actually that's not completely true. POV-Ray performs some optimizations
in transformations in order to avoid making a transformation matrix.
If you eg. create a sphere and translate it, POV-Ray will change its
center.
It's better to explain transformations in a more abstract level,
without going too deep into details. From the point of view of the
user it doesn't really matter which way transformations are applied
(ie. by modifying the object parameters, if possible, or by creating
a transformation matrix).
