Yeah; if you pull it gently (and if you're in the right position) you get a harmonic, but if you pull it more, it drops down to the "regular" pitch. As for the actual physics, I'm not certain whether the non-harmonic is caused by the extra tension, or the width of the finger[1], or what. [1] if you touch the string lightly, you only have a small area. But if you pull the string a lot, your finger occupies an arc with a wider angle (albeit still on the order of 2-3 degrees). This wider arc will deaden a lot more vibrations than a small-area touch.
