[GAMEPLAY] Visual Bug when Mordekaiser Successfully Ults Cho'Gath

I noticed in a bot match earlier today that when I killed Cho'Gath while my ult was ticking down him as Mordekaiser that the indicator that is normally given to Cho'Gath to indicate when he is able to execute another champion with his ultimate ability was visible to me; as Mordekaiser for my enemies even though this had no benefit or abusive feature to it, it was still confusing. To replicate the bug I did as so:

1. Place ult on Cho'Gath,
2. Kill Cho'Gath to obtain his "ghost,"
3. Steer the ghost of Cho'Gath within some distance of another low-health enemy champion.

I have attached a screenshot of the incident and I found the bug to be seen time and time again, as I have tested it in a custom match three times now.
