Question about heater hose connections on 273 2 barrel (1967 barracuda)

Hi, I have a question regarding the two orange hoses in the attached pictures on my 273 2 barrel 67 Barracuda.

The first one is an older picture of my car and the two orange hoses looks like a normal setup that I have seen on other cars along with my previous 67 barracuda.
The second picture is the current connection, which has one orange hose going to both inlet/outlet connections on the firewall, and a shorter orange hose from I think the water pump to the engine.

Does anyone know why a previous owner would change the hose connections like this, or if it is okay?

I was going to buy two new hoses and reconnect a hose to the inlet and one to the outlet on the firewall, but wanted to see if anyone has any insight into this.

Thanks in advance for any info.
Shane
