Sadly, this is not correct. You see what color of Materia is active at a specific time, as shown with Yazoo and Loz near the end. We see that Kadaj has a blue/green (I thought it was green, some say blue, so whatever) glow on his arm, implying that materia color is being used. Therefore, he is using that color materia to summon Bahamut Sin
The glow on Kadaj's arm was different from Yazoo and Loz's at the end. The materia that Yazoo and Loz had in there arms was actually glowing in their arms, you could the individual materia that they had. But with Kadaj, his arm was letting off some sort of blue-green flame. The same flame can be seen when he is talking to the children at the Forgotten City. And I doubt he is using materia then.
I think that Kadaj's blue-green flames look an awful lot like the Spirit Energy that emits from Cloud when he is using a Limit.
Actually, you do see the blueish flame around yazoo and loz's arm at the end.
The "flame" around him in the forgotten city, I admit, it doesn't look like he's using materia here. Not sure about that.
Also, I'm not gonna let it go mainly because I like debating these kinds of things, lol
