Sejuani's Bola Get's Knocked Up

While playing as Sejuani I ran into a situation where if she fires her bola and a fraction of a second later she get's knocked up by Cho Gath's Q the bola get's knocked up too and flies over the enemy team. I don't know if the bola was knocked up because Sejuani was knocked up or if it was knocked up because the bola was in the AoE of the rupture as well.

Tried posting a video of it but the game is not uploaded on op.gg.
