Precognition only allows the user to see one possible future. Itās already shown that even with precognition, he has no viable defense against Sansui. In a hypothetical scenario if these two were enemies. Thereās the high chance his precognition would only result him in seeing darkness aka nothing as he would be dead in the next instant.
In previous chapters his fights against Sansui using precognition still resulted in his defeat.
1st fight: he predicted Sansui would strike him a certain way. Sansui changed his mind in a momentās notice and defeated him a different way.
3rd fight: he saw the future but was unable to determine how he lost. In the precognition vision. He saw Sansui, then immediately saw the sky. He had no way to defend against that. There were no clues for him to use and his current skill set all being used is still no match for Sansui.
