Though I'm no expert on the source, an educated guess would conclude this:
An application needs to define what type the information is, e.g. a float or
a vector, to allocate the appropriate amount of space. POV-Ray probably does
it by reading the information and finding it's type along the way (or
something like reading it into a buffer, finding the type, casting it and
handing it back to the POV-SDL environment).

If you've set the type before, POV-Ray doesn't have the flexibility to
adjust the type by itself, as clean and proper programming would disallow
such behaviour (who has ever heard of a programming language which recasts
types as it sees fit?!).
