Can Ekko hit you 3x with his Q?

Ekko throws out his Q, the grenade stops, and then comes back to him. So, with that in mind what if I ult while it comes back.

Ex. 1- Ekko (running from someone) -> Enemy -> ult hologram 2- Ekko (running from someone) -> Enemy -> grenade (1st hit and stops) -> ult hologram 3- Ekko (running from someone) -> grenade (2nd hit and returns) -> Enemy -> ult hologram 4- Ekko (using ult) -> grenade (still on its way back) -> Enemy -> ult hologram 5- grenade (still in flight) -> Enemy -> Ekko (location after ult) 6- grenade (recalculates Ekko's current location) -> Enemy -> Ekko (location after ult) 7- grenade (does a 180 to go to Ekko's current location) -> Enemy -> Ekko 8- Enemy -> grenade (3rd hit and procs passive) -> Ekko (uses speed buff from passive to escape) 9- Enemy (crying and typing in all chat, "Ekko op") -> Ekko (laughing while returning to base) 10- Enemy (still crying) -> Ekko (laughing while returning to base, 1sec left) -> DRAVEN (full build) 11- Ekko (Dead at team base) -> DRAVEN (LMAO for breaking his highest bounty record) 12- DRAVEN carries team to GG XD

Someone test this please or provide a link to someone who tried this already If this does work and people start doing this in games, technically, not my fault; YOU are the one that produced the test/link XD
