Most likely they are allowed to proc at the same time. With 2 glasses you have a 1% (0.1*0.1) change of proccing both at the same time for 4x multiplier. When you have 3 glasses you have a 8% chance of a 4x crit (0.1 * (0.9*0.9)) and so forth. If you have around 50 it makes sense that there would be a decent change of getting 2^10 crits, ie 1048 times your "base" damage.
