Products aren't hierarchially ordered first by type, then by colour, then by material, etc. These are all attributes that have multiple possible orderings (or no order at all). Of course, if the site is designed such that it forces you to pick those attributes in a specific order, that URL scheme would make sense (but that would be a poor design for other reasons).
