Same airline does not always mean the same terminal, but if on the same ticket, I think the passenger should be protected.
T3 is totally out of the way from T2 and T1. If there is no airside transfer (I don't know if there is), it is very time-consuming passing through immigration twice and security once and travel between the terminals several km apart.
