Which ability does Yasuo Windwall blocking doesn't make sense

Yasuo Windwall is supposed to block enemy Projectiles, yet sometime, I feel like it doesn't make sense. For example, Lillia's R and Smolder's R. Idk, it just feels wrong for some reason.

Any thoughts?? And also any other abilities that Yasuo Windwall blocks??

Oh btw, I'm just someone who's still new to LoL, so I'm not looking for trouble. I'm just curious to know.
