Since we are talking about leveling a Chocobo, relying on doing enough damage to a pink tagged mob is unreliable at best. Therefore it is far better to make sure the enemy health bar and name tag are red to almost guarantee credit for the kill.

And also, attempting to tag another groups kills is not so much a good idea as you will only aggravate those in that group. Plus it is not very polite to the victim of this.
