Not necessarily correct, no. Remember, with LC the car is sitting there with the clutch/es open and no brake applied. It can easily roll.
Here's something to try: stop at your desired "launch site", put the car in neutral, and rev it to 5k RPM or so. Does it roll? If not then it will probably stay put if you try to use LC right there too. If it does roll though, then it probably won't stay put with LC either. Just a thought.
