I was just looking at the final positive mutation - available once only - and suddenly realised something odd about the wording.

When you Treat, remove all the cubes of this color from your city.
I had been reading this previously as "upgrade this color to be like the Medic pre-cure for any character". However, the Medic removes all cubes of the color he is treating. Reading the upgrade literally, if it was applied to Blue and you were in a city with (say) two Yellow and two Blue cubes, you could "Treat" (to remove a Yellow cube) and as a result of the mutation, both Blue cubes would vanish as well!
(Whereas the Medic for an action could remove EITHER both Blue OR both Yellow).
Is this correct, and the upgrade is actually more powerful than the Medic, or does it implicitly only apply when treating the color it's affecting?
