If they tag the first group RIGHT after they pop sprint, they're going to have ~18 seconds worth of sprint while everyone else will had 10 seconds and it will be harder for them to keep up. If they pop sprint more than 10 seconds before they tag that first group, they may have well just popped sprint after the pull.
Healers and dps don't get aggro on trash until they hit something or heal the tank, so there's no problem with them sprinting after the tank hits a group.
