The reason you use a glow plug reamer is that there is carbon buildup around the tip.
This causes a carbon (insulation) sock to form over the electrode.
The reamer breaks up the shell to powder that will pass through the pre-chamber and out the exhaust pipe.
Here is a thread that should answer the rest of your questions.
