They may cause induction to the free wires and hence to the light load. For example in a typical circuit assume there eight light points and seven of them are on and one is off. The control wire of 8th lamp will get voltage induced from all or few other wires. There will be a good glow. This will be with normal wiring pattern.

Charging by Induction

Induction charging is a method used to charge an object without actually touching the object to any other charged object. The process occurs in two steps. The first step involves bringing a charged object near the object to be charged so as to polarize that object. With the second object still held nearby, the opposite side of the object to be charged is touched to a ground, causing …

Another reason is that while the coil inside the induction cooker has multiple turns and might have 200/300V AC which is quite high, the pot is not a coil at all, there are no turns so the voltage difference induced into the pot (which is AC too) is low and gets equally distributed in space, can't build up to a high value like it would on a coil.
