Correct.
So far, the game pits White's edge territory against Black's outer influence. Black's play at 1 maintains consistency. If White guards his profit with 2, Black keeps pushing at 3. Black makes an important forcing move at 7, before setting up a magnificent framework with 9, the scale of which outdoes even Takemiya.

White variation.
If White tries to poke through to the center with 2, Black has the wedge tesuji at 3. After the 2 pushes at 7 and 9, A and B are miai for Black. White will suffer greatly.

Horrible.
Hopefully, no one considered the Black extension at 1. By itself, this play is large, but when White advances easily into the center with 2, Black's game falls apart. Black can try to develop the 3 stones below and a framework above with 3, but White has the standard shoulder play at 4. After White 6, Black's prospects for a needed large center are evaporating.
