That is correct. The moving white bar is to look for tearing. The text, and bursts, are to look for consistent motion. If you see a tug, or jerk, something is going wrong. 24p has a fixed amount of judder. If you read the ASC book, you can only pan a camera so fast at 24p. The motion on this pattern moves faster than that.
The 24p motion can be improved with a display that has a true off state or uses something like black frame insertion. It can also look better with motion interpolation modes, but that changes the look, which is not something we find desirable.
Some displays assume the input will be 24 or 60 Hz and not 23.976 or 59.94. This will result in a glitch every n seconds. (16 in the 59.94 vs. 60 Hz case) Even though we say 24, 30, and 60, they are really 23.976, 29.97, and 59.94.
Hope this additional info helps.
