In the example diagram on page 9 you state the Z-Axis scaling can be used in addition to Y-axis scaling but use a load balancer rather than a router. Is this not an error? Should the load balancer not be replaced with a router>

Sorry for the delayed response.

That diagram only shows Y axis functional decomposition and X axis scaling.
If the application used all three then you would first functionally decompose into services (y-axis).
Each service consists of a router, which route requests based on some attribute (Z-axis) to sets of load balanced service instances (X-axis)
