In the original Terminator, why does Kyle Reese refer to the T-800 as "he" instead of "it?"

I was just thinking about the scene in the interrogation room. He says something along the lines of, "He'll find her... that's what HE does. That's all HE does!" Now, being that Kyle Reese is actually from the future, and not crazy like the psychologist believes, wouldn't the lines, "That's what IT does. That's all IT does!" make more sense?
