Besides, If you have two or three hots exiting the panel by the same couduit, but will serve different areas of the house (like, all over there), it is common to only run one neutral and the splity it up at a junction box, downstream. Not necessarily the best job, but I have been told by various inspectors (code) that it is legal.
an example of the mantra that code is a MINIMUM standard, NOT the lofty goal of all attainment.

When you have black and red wires togehter it is a good sign that they are sharing a nuetral as suggested above. It is deemed as legal in many areas. I would suggest verifying the black and red wires are on seperate phases in the panel board, if not it needs immediate attention. They also should ot control any arc fault devices.

?/3 wire instead of ?/2 and sharing the neutral .
What I mean by /3 instead of /2 is it’s the same amount of conductors as used on a three way switch except in this case as Mr.Decker said the branch circuits where split up in a junction box some where else in the house.
Hope that makes sense.I know what I’m saying but might not be saying what i’m knowing.

You are describing multiwire circuits AKA Edison wired.
The number of red wires in the picture would seem to indicate that.
There are good reasons to do it. Voltage drop on a long run is one reason to do it. It is one of those cases where your sure test will give you a misleading indication.
