Difference between disabling the 2.4 GHz network in a Cisco WLC and disabling 2.4 radios in APs ?

I've been seeing conflicting info on the web. I hope you can clarify.

The following steps will disable the 2.4Ghz Network in a Cisco WLC

1. Wireless > 802.11b/g/n > Network; 2. General; 3. UNTICK 802.11 b/g Network Status 

This command will disable the 2.4 GHz radio in an AP

config 802.11-abgn disable [AP NAME] 

What is the difference?

Is the disabling the 2.4Ghz Network enough? or will the radios in the APs still be on and broadcasting some kind of frames to the air?

Thanks
