No, it's from a video that creates a 3d engine from scratch :

That doens't change the fact that it is very similar, if not exact, to a DirectX projection matrix.

If it is an orthographic projection, we're done. If it is a perspective projection, we must take into account the divide by Zin that will happen.

 Why's that, why does orthographic projection have no division and perspective projection does have division?

Because that is what makes a perspective projection have perspective. The division is what makes things shrink as they move further from the camera.
