Weird Thing About Tahm Kench's Devour

When an enemy dies inside of Tahm Kench, why doesn't he "digest" them? It's weird that the character's body just pops up outside of him; it'd be more true to his character if the enemy model disappeared. It's not like the dead bodies need to exist on the screen for gameplay purposes when the death marker is labelled on the map, either.

League has a lot of little aesthetic pieces and easter eggs which make the experience that much more enthralling. So, I'm wondering why something so obvious was just...not done?
