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.
