I'm guessing that this means two are being fed from the first. This is way more loss than you need to have.
So, he ended up using 8-way splitters in all 3 places. The unused outputs were terminated, so I don't think I'm losing any significant signal. However, it does seem like a waste.
I'd have them come back and use "smaller" splitters to gain resistance against rainfade.
The SWM output and the receiver's input levels shouldn't have more than around 25 dB of attenuation and an 8-way to an 8-way eats all of this up and some more, so you've lost all your "system reserve" for weather.
