221g - what does "Status Updated Date" mean???

[Foreigner2012]

I was checking my case status on a new link on the Dept Od State site

(https://ceac.state.gov/CEACStatTracker/Status.aspx?eQs=WwjqOlbeRYzCYubaSQI+RA==)

My question is :

I see that my "Case Creation Date" is accurate (aug 24th 2012) and I see also an "Status Updated Date" which shows Nov 5th 2012.

Does anyone know what the "Status Updated Date" means???

And yes it also gives the following description below

"Your visa case is currently undergoing necessary administrative processing. This processing can take several weeks. Please follow any instructions provided by the Consular Officer at the time of your interview. If further information is needed, you will be contacted.
