That is actually quite common, and happens to all our motors after every run, we just don’t know it.
As the motor is dying off, if it doesn’t quite get over it last compression stroke, it sort of falls backwards, and the impeller blade will flip back as it does so.
There are guys out there that are very anal about this, and after running the motor, will pull out the recoil, and let the compression "bleed off", to ensure that the impeller blades don’t flip backwards like that, then slowly let the recoil retract.
I guess its good practise, but as I but in brand new impellers in my motors every couple years I personally don’t worry about it, UNLESS I know ill be storing the motor for a while on the rack, then I do it.
