given a transaction like:

https://blockchain.info/tx/ec3d03436e365d6c739cd020e0da705cdbd6468670344fc4363f0ca5955da4a2

It depends a bit on how you define the word "owner".  It also depends a bit on how much effort 2 people might want to put into sharing in making the payment.

Generally though, you'd mostly be safe in assuming that a single entity (person?) has access to the private keys associated with BOTH those addresses.
