Sorry, but this is NOT the "proper" way. It is one way.
What is the "proper" way? Or were you just saying that there is no one "proper" way?
If the circuit in question is NOT a MWBC, either feeding through the device and pig-tailing is generally acceptable. Some AHJ's require and some ECs prefer to pig-tail. For MWBCs, feeding through the device isn't allowed. Obviously, in the case of GFCI receptacles, you have no choice but to feed through if you are also protecting loads down-stream.
They don't have to be pigtailed on non MWBC circuits but:
must be pigtailed on MWBC installation.
