If you read the description of v-modell carefully, you would have realized that v-modell isnt a strict process and does not define in which order certain steps have to be made.

Before tailoring (which can be used to create an agile process as much as waterfall btw) it just tells you WHAT has to be done and not HOW it has to be done. The order and iterations of each step is defined during the tailoring step.
