Week 3, Desperado quest can be completed with Leona instead of Hecarim

I played an ARAM as Leona, landed e multiple times, and when the game ended I had the quest completed. The section that says "As Hecarim, knock back an enemy champion with Devastating Charge (e) 5 times" was full, while the "play 5 games" was only filled up 2/5 games. Edit: looks like it can be done with multiple champions.
