Hold case/221 G & Refusals/214B

I appeared for my L 1 B Visa interview at Chennai on 30 -Jul - 2015.

After question and answers session ,the officer returned back my
passport along with blue color slip 221(g) and stamped I-129(S) that
not clearly approvable.

The officer has ticked on the box of slip 221(g) where below comment
was mentioned.

“Your blanket L -1 application is not clearly approvable under section
8CFR 214.2 (I)(ii)(D) and INA 101(a)(15)(L). You may not reapply using
the same petition. but may reapply as the beneficiary of and approved
individual petition.”
However, when I saw my status on link :
https://ceac.state.gov/ceacstattracker/status.aspx

This shows a message that Administrative processing is still in
progress. Please find attached status screen print.

Also, I have called in the customer support number : 91-120-4844644,
they told me that 221(g) is not a rejection, the consular will ask for
the proofs then after the consulate will call me for further
processing.

Can any one suggest me what it means
