You are correct!

I think white plays 0-0 before Nc3 in most games. I would normally check ECO, but I do not have it on hand. I checked the Chess Assistant data base of games. It's a little confusing as many move orders are possible. After,
1d4 Nf6 2c4 g6 3Nf3 Bg7 4g3 0-0 5Bg2 c6, White plays 60-0 twice as often as he plays 6Nc3. It is a sizeable number of games either way.

Lemos makes, and underlines, the point that white should prefer 6Nc3 to 60-0 (in his repertoire).
His exact move order (beginning chapter 3) is 1d4 Nf6 2c4 g6 3g3 c6 4Nf3 Bg7 5Bg2 0-0, and now 6Nc3!

"White should delay castling for a couple of moves ..."
Lemos, Damian. Opening Repertoire The Fianchetto System (Kindle Location 1456). Everyman Chess.

It is at least worth noting that this move order is not generally going to useful for people who start from a 1.Nf3 move order that do not want to commit to c4 so soon, e.g. those that play 1.Nf3, 2.g3 and then 6.b3 against the KID.

GM Lemos offered a new wrinkle in his opening repertoire:

https://everymanchess.com/products/opening-repertoire-the-fianchetto-system-weap...

He recommends playing Nc3 before castling:
1. d4 Nf6 2. c4 g6 3. Nf3 Bg7 4. g3 O-O 5. Bg2 c6 6. Nc3! d5 7. cd5 cd5 8.Ne5! 

9.Bxd5 Nxe5 10.dxe5 Nc6 11. Nc3 and after a few accurate moves by Black: White can't really lay any claim to an advantage here, although there is still some life in the position.

I checked in little bit more detail: The Schlechter chapter has 35 lines about 10 of which transpose after 7.Ne5 ... 8.cxd5 cxd5. The simplest option may be to buy and make use of their return policy. The only other possibly relevant course I could find is Svidler's Gruenfeld which covers 8.Ne5 Bf5 9.Nc3 Ne4 from the Black side.

The chessable Lifetime Repertoires: The Catalan by Narayanan  suggests 7. Ne5 and 8. cxd5 in case of 7...Ng4, 7...Nfd7 and 7...Be6. So you might find something of interest there.
