Is this true or not?

It depends on if the trigger threshold is on going high or going low. On an HEI, it is triggered ON/closed going high or around 1.6v depending on the module internals and OFF/open around 1.4v. If the value is between the two states, the module can end up in either state
That kind of makes my point

The reluctor is creating a voltage but only when it is rotating and if it is below a level it results in an open to the coil meaning no charging of the coil.
