I don't think he had the actual ten-tails. He only had his chakra probably. Hagormo and Hamura sealed the Gedo Mazo, creating the moon. The Gedo Mazo was kind of the depowered version of the ten-tails, but it can be interpretated as being the depowered "body" of the ten-tails. So Hagormo hosted the ten-tails chakra, but not the actual ten-tails like Obito or Madara.
