There could always be a first time though.

A solenoid can easily stick if moisture causes corrosion.
It depends on climate, starter location and starter design. Certainly not impossible.
The solenoid is grounded through the body of the starter and the brushes play no part in this.
This can easily be shown by connecting a 12v feed to the solenoid ignition switch and grounding the solenoid body.
You could have badly worn brushes or no brushes at all in the starter yet still engage the solenoid.
