I fully understand what you are saying VOS, the point I was trying to make however was that a receiver with low RF signal (too any splitters, too long cable run, etc) is more likely to "fade" [(first than the one with higher RF signal) (even if both receivers have the same transponders numbers)] due "atmospheric" conditions, be it rain, extreme heat... as these can cause signal attenuation.
"If you say within the loss range", this isn't a problem.
Now I can mockup a setup that would be like what you're saying.
Step 1: exceed the recommended loss from a LNB to the SWiM [8 or 16]
Step 2: have a very long run to a receiver.
"Good weather" will have the SWiM AGC compensate for the "excessive" LNB to SWiM loss.
As the signals weaken, the longer run can drop below min due to the AGC running out of range, while a receiver on a shorter run may not.
With a SWiMLNB you can't, because the "weak link" is the loss between the LNB & SWiM.
The LNB to SWiM loss really needs to be addressed when you feed more than one SWiM or have to locate the SWiM farther from the dish than the 45' recommended.
