What they mean is, it won't get any thicker than 10 when cold or thinner than 30 when hot. It still thins out plenty as you know.

5W30, 10W30,10w40-whatever the first number is, is the base weight-what they Oil Manufacturers use is called Viscosity Index Improvers (which are generally polymers)-here is a little bit on the subject:
