As far as I could understand, Rukia and Renji first felt the heavy reiatsu when they arrived at Hiyôsube's palace. It seems he possess much greater reiryoku than the other RG members, or something. And being the apparent leader of the RG, it would make sense.

If not that, there must be a much higher reiryoku level at his palace. Or his palace is just located closer to the Soul King's palace for some reason.
