Flash Cache and Pool in the same system

Just need to verify that I'm reading this correctly. According to the latest C. documentation:

 

You can use Flash Pool aggregates and the Flash Cache module (WAFL external cache) in the same
system. However, data stored in a Flash Pool aggregate is not cached in the Flash Cache module.
Flash Cache is reserved for data stored in aggregates composed of only HDDs.
-- Data ONTAP 8: Physical Storage Management Guide

 

That says to me that if a system has one aggregate and a cache card, the card will effectively be disabled when the aggregate goes hybrid. Is that correct?
