Yes. But the bevel gets broader. (The height of the bevel)
Ah no, again in theory the bevel should not get broader. You need a certain width spine for a certain size blade to get a 17 degree bevel. As the spine narrows and the blade size shrinks the bevel should remain the same width. That is the theory but in practice all bets are off especially if the spine wears faster, thins, than the blade size reduces.

A good example is a near wedge with heavy hone wear and it shows a wide bevel. You likely need to add multiple layers of tape to compensate for the heavy hone wear and your new bevel should be thinner than the original.
