Why should a kit that both heals and provide something else be disqualified as a healer? Because they're overqualified? "Healer" is someone who heals. That's all the label means.
Perhaps because it still puts out more damage than non-DPS or more tank-y-ness than a non-tank than it puts out more healing than "has lots of healing, but isn't quite a 'healer'" non-healer?

If the criterium is solely "Is its output sufficient to do X," you could easily have a job meet that criterium for all three Roles, especially with the way things have been going of late.
