Both movies are at 24fps (assuming NTSC), but your eyes will definitely pick up less motion blur on the 120Hz screen.

I'm not sure that's a good explanation of that test. You'd actually be testing the ability of the LCD to change its pixels quickly, and what you'd see are pixels in transition, not one image followed by another distinct image 24 times per second.
Two LCDs both at 60 Hz could have very different amounts of this kind of motion blur. Or, put another way, one screen capable of multiple refresh rates will have the same amount of this blur no matter its refresh rate. 24 FPS material played at 24 Hz will look identical to the same material played at 120 Hz. There is no difference between a frame held on the screen for 1/24th second and the same frame refreshed 5 times in 1/24th second, since nothing is actually changing in those refreshes. The response time of the LCD is only a factor when you go to the next frame, and that will happen 24 times a second, regardless of refresh rate.
