*sigh* Yes, because the starter motor brushes are grounded through the armature and to the starter body. Take a look again at the circuit diagram that Dave posted. If it helps, trace the two solenoid circuits in two different colours - the paths are obvious and obviously different.

You've also said that solenoids don't stick when they can but to be honest, I'm not here to debate.

No, I said there are two circuits in the solendoid which have two different grounding points. See my point above.

For some, it would seem that blind luck may well be the correct answer.
