Extra exposure increases density, hence you get a thinner image on a denser negative. Minimum density increases faster than maximum does with increased exposure. This also causes increased graininess.
Your use of the word 'thinner' is making no sense in this context unless you are talking about the print getting thinner, less dense, because of the negative is more dense, thicker, and blocking more light in the enlarger.

What am I missing in your point?
