Yama The White fight

It is possible to have both attacks from the boss at the same time, meaning an impossible way to avoid or counteract the mechanics. I can have the 6 mirror clones on the pylons shooting chaos orbs at me while having the 4 clones on the ground scattering and having to stand in a small circle. How am I supposed to stand in the small circle and avoid the chaos projectiles at the same time?

Also, the chaos ground effect lingers after the boss is defeated.
