Reflecting on a Reflection description

I was quite surprised when I arrived at the Reflection chapter in my self training book, because on the first page I found the following:

Reflection is useful anytime you need to examine or run code that isn't available at runtime.

MTS Self-Paced Training Kit (Exam70-536): Microsoft .NET Framework - Application Development Foundation, SECOND EDITION

After I read this, I fear I really need to study Reflection, because the reflection I studied at the university, was exactly the opposite. But I guess just because reflection means something in the Java world doesn't mean that its the same on .NET.
