The idea is that we are trying to create conflicts between namespaces. If we
add random address, and then delete the same address - nothing interesting
happens. But if we delete some another random address - we will eventually
occupy some share of IP-addresses - and conflicts start to appear. I'll mention
this in comment in next version.
PS: I agree with other comments from your side. Will fix them.
