It definitely can't be Overdrive because the volume is too low and it has no metal. And if the sound after the break really is Neutral then also the CVT's analogy between Neutral and whispering/speaking quietly doesn't hold true. At least I wouldn't use that when whispering. It feels like a different way of producing sound compared to my "normal voice". One of my teacher stated that both of the sounds are Neutral and CVT doesn't make a distinction between them. So guess, that's how it is, but IMO they should be described separately since they have completely different sensations and can that way cause confusion. For example if you're trying to do a crescendo to metallic modes, the break happens only with the other. To me it seems that the lower you voice is (bigger vocal cords) the more distinct the difference is between these coordinations naturally. Of course everyone can learn to yodel and make the break more pronounced.
I'm gonna call the other one Neutral and the other one Falsetto.
So here's a Falsetto glissando funkypou asked me to perform. Very easy, since Falsetto cost like nothing until the very high part of the voice.

Here's the first line of Mad World sung in Neutral (the sound I'd like to be able to do in higher pitch.)

And here's the same with Falsetto, which I don't like too much. It is mostly usable as an effect only. And of course you need it when doing vocal breaks. Unlike Neutral, Falsetto has a lower limit around C3-E3 so it doesn't function very well here and volume has to be quite low in order to avoid breaking.

It's hard to make a very distinct break between these described sounds and they connect pretty well.
In the CVT Sound Library samples I mostly hear that "Neutral" is usually used in the lower pitches and "Falsetto" in the higher pitches.
