The private key determines the public key, which determines the hostname.
The public key also determines the position on the HSDir hash ring.

All services with the same key upload their descriptors to the same HSDirs.
Each service uploads at a random time.

The HSDirs keep the most recent descriptor.

It's a crude form of load-balancing.
And some large onion sites use it.

(The details are slight different in v2 and v3.
But it works pretty much the same in both versions.)
