Actually, I believe we do not have a birthday paradox issue in this case. The birthday paradox would exist only if ALL 1.2 million self-drawn prefixes would see each other. However, in our scenario, the merging of two enterprises, only the two local prefixes may collide with each other. They can not collide with the other 1.2 million or any other number of prefixes out there. Thus, the probability remains 2^-40.
