I don't see how.

Kaz means that a CSPRNG is required for Maurer's algorithm. My 
explanation of Kaz's meaning is by way of a parallel. Consider an 
algorithm for filling a bucket with water:

Step 1: place the bucket under the tap
Step 2: turn the tap on
Step 3: monitor the flow of water
Step 4: when the bucket is full, turn off the tap

At no stage does the algorithm say "ensure that the ambient temperature 
and pressure are such that the water is in liquid form" or "ensure that 
gravity is working" or "ensure that your bucket has no holes except the 
one for allowing water in at the top", but we may safely deduce these 
facts from the context, and anyone who needs these conditions to be 
spelled out may experience self-esteem challenges when their IQ is 
compared to that of a brick.

Kaz - fair summary?
