Odd copper fin BB piping

in THE MAIN WALL
I have a zone with two supply and one return. All 1” copper. It used to have a single system pump on the return. Anyone see any harm in putting the pump on the supply side as I typically do or safer to pull from the single return? One supply goes to the front and one to the back of the house and the return goes down the middle of the house but all disappear into a finished room so I can’t follow the pipes. Thanks.
Just a guy running some pipes.

    On the supply, "pumping away" from the PONPC.

    That's a split loop which is very common on larger series loop systems. It helps to even out the SWT to the BBs. There may be balancing cocks somewhere after the split.

    You can choose to do what you want, but you cannot choose the consequences.
