Does anybody know the reason why a P6 2000 ( 1972 ) has 2 sump plugs ? I thought I was seeing things . I don’t think I have ever had another car with 2 .

The oil cooler circuit on TCs does not go through the sump.
The second sump plug is also convenient if you want to install an oil temperature sender unit, or and oil heater element.
It's the only car I've ever come across that does drain the oil cooler into the sump. It's a lot more efficient (in terms of cooling) to force the hot oil through a cooler then straight into the engine than to return it to the sump.
