What this shows is nothing more than the need to be clear and thourough when asking a question. Nothing more.
When Celtavian asked his question, he presented no information to the CS reader. All he asked was, "Does Death Ward protect against the Phantasmal Killer spell?"
The CS guy isn't going to bother looking up a bunch of rules, he's just going to respond with his opinion. There is no guarantee as to just how informed that opinion is.
Pielorinho got a correct response because he presented facts and quotes to establish a more thourough basis for the CS guy to better answer the question.
Nothing more. The second response is much more believable because the question was better asked.
OK, here's an analogy...
I say, "My car is silver."
Am I telling the truth? Maybe.
Now, I tell you, "My car is silver. Here's a picture of it (yes, it is indeed silver). Oh, and here's a copy of my current registration showing my name, address and the color is listed as silver."
Which one is more believable.
