"Pulldown" refers specifically to the technique used to convert 24p footage to 60i. It is used by the telecine process in order to turn film (which is always shot at 24 fps for "normal" motion) into an NTSC video signal, which is 60i. Please read the relevant Wikipedia article for an explanation on why it's called "pulldown" in the first place.
You're confusing pulldown with interlacing. Interlacing merely refers to an encoding scheme used for the efficient transmission of a video signal. Deinterlacing refers to any method of constructing a progressive signal from an interlaced signal. That's probably why you assumed that "removing pulldown" (AKA deinterlacing, in your mind) meant that you would be getting a 30p signal from 60i. While some deinterlacing methods weave the fields together (getting you 30p), the reverse telecine process actually reconstructs the original 24p signal through removing the pulldown scheme.
The vast majority of consumer and prosumer 24p camcorders use pulldown because the manufacturers want the video to have backwards compatibility with NTSC video systems, such as older TVs. There's nothing weird or unusual about it. There should be no more confusion now.
