How did Sugimoto get downstairs so fast?


In the [S4E1](https://youtu.be/Aj1j36Lc22Y?t=54) of Golden Kamuy, after
kicking down Sugimoto, Vasily rushed downstairs, leaving Sugimoto behind. Then
Vasily was trying to escape out of the house when he was suddenly grabbed by
Sugimoto from behind a shoji.

How did Sugimoto get downstairs so fast and ahead of Vasily?
