Does block award go to miner address or owner's

I am reading mining process spec. It says:
The owner address is the address that created the miner, paid the collateral, and has block rewards paid out to it.

However, in my test, I found all the block award actually goes to the miner address, instead of the owner’s, which is the filecoin node’s wallet, I think.

Will this be changed later, or my understanding is incorrect?
