From there, you would have a check valve and a pump that moves the hot water from the tank, to that distant fixture, back through the return line that was added, and into the hot water tank via the cold inlet. With a home run PEX system, you don’t have a most distant fixture.

What are the advantages of using PEX plumbing?
