Yes it's a renewal after the first 3 years.
What link you have forwarded, that is in the extension approval process, where USCIS toughen the process, which we realized and we had to forward lot of extra documentations etc. But My VISA extension application approved couple of months back.
Now, I need to do stamping if you go for a vacation/out of US. And that stamping request has to be done through my company itself.
