Yes it is.  All Mopar big blocks are this way.

How did all of this start?

It sounds like there were no leaks before, and the decision was made to have 
a shop replace the upper hose. What "lower hose part" is being referenced 
here? Was the lower hose being changed also, and a problem discovered with 
the spot where it connects to the housing? Was the old water pump removed 
and reinstalled without replacing it?

As has been stated, water could be coming from above and then dripping down 
to the lowest point before it can be seen. The water pump shaft seal or 
gasket could be leaking. Bottomline, there's a leak and it needs to be 
fixed. Heck, I have seen a pin hole leak in a hose (check both radiator 
hoses and heater hoses), or in the radiator itself shoot water at the front 
of the engine, and appearing from below like a leaky pump.

If my memory is working today, on the 413, the water pump can be replaced 
without removing the entire housing, in fact that is the way that they 
usually do it. I don't recall if the same set up exists on the 440, but the 
source of this water leak shouldn't be that difficult to find. If the shop 
took the car apart and didn't put it back together correctly, they should be 
able to figure out what they did wrong, or maybe they aren't a very good 
shop in the first place.
