I agree with that advice. The fundamental logic is that the whole house 
protector takes care of what comes in on the power line, and the SurgeX 
boxes take care of what is induced by a strike on wiring inside the home.

Since I began with SurgeX units before I learned about the availability 
of whole house units and have them on all my sensitive gear, I've not 
done the whole house unit.  If I were starting from scratch, I would do 
a good whole house unit first.
