The issue here I would say lies with the fact that these two rides are completely different, yet in an attempt to probably save money not needing to manufacture a new chassis cover, they've cloned the Swarm trains...
It's not a clone, whereas with Disney, even their clones usually have completely different features or layouts (Raging Spirits vs Indiana Jones, the MMV Indiana Jones rides, Matterhorn/Space Mountain)... Most of the time the obvious clones are the flat rides or indeed, the Paris/Cali versions of Tower of Terror... So really the majority of Disney clones are because you can't do much with the theme of a flat ride... Although of course the issue of having 3 clones of the same ride in one park is a different arguement all together...
