Why might it be silly to have a 2-step Wizard?

In reference to 'Designing Interfaces' it's stated that it's silly to have a 2-step wizard. What are the reasons for this and is it really all that bad to have a 2-step wizard process?

In either case, the hard part of designing this kind of UI is striking a balance between the sizes of the chunks and the number of them. It’s silly to have a 2-step wizard, and a 15-step wizard is tedious. On the other hand, each chunk shouldn’t be overwhelmingly large, or you’ve lost some benefits of this pattern.

For my interface there is a 2 step process and I feel that in order to visualize that in a recognizable manner it would be best to use a wizard-like interface.

Would this really be silly?
