It could, but it shouldn't if properly made.
For one thing, it's got 4 straps. If any 3 straps or any two opposing corner straps are intact, then it should probably not fall down. So there's some redundancy.
Aside from that, use a worm drive[1] between the motor and the pulleys. As long as the gearbox is intact, the weight of the furniture won't be able to turn the output gear.
If you want more assurance than that, put some kind of extra brake or lock on the pulleys or drive shaft. Maybe a pawl[2].
