Yes, but we have that problem now, it is not a new one.

My intent for including this clause is to eliminate potential 
inequities, right now if you have 1000 hosts you can justify getting 
IPv4 address space, without being multihomed.  Therefore, you can 
justify getting IPv6 space. Because anyone who can get IPv4 space must 
be able to get IPv6 space to enable transition.

What I am trying to ensure is that the moment after IPv4 run-out occurs 
that someone who qualified for both IPv4 and IPv6, still qualifies for 
IPv6 even though there is no longer any IPv4 space left.

Long-term term I would prefer this clause were eliminated or that it 
wasn't necessary.  However, I believe this cause is necessary in the 
short-term to eliminate any discontinuity at the moment of IPv4 run-out. 
  My intent in having it as a separate clause, is to make it easy to 
eliminate at the proper time, like a year or two after IPv4 run-out.

I open to suggestions for a better way to achieve this goal, but I think 
it is important that the moment of IPv4 run-out doesn't accidentally 
change who is eligible for IPv6 address space. I believe this is 
consistent with the current policy language and necessary during IPv4's 
run-out phase,
