Oppenheimer-Snyder Collapse

I have read the Oppenheimer-Snyder collapse is significant in the sense that it was the first work which treated the problem of black hole formation under gravitational collapse. The model assumes a homogeneous ball of pressureless dust.

My question is: Is it not trivial that such a model will lead to black hole formation? All matter moves towards the origin, and there will be a point in time when the matter all congregates within the schwarzschild radius, forming a black hole.

Am I oversimplifying things?
