That seems like a fine editorial change.  This text is just from the 
current policy.

Yes, the intention is that only one of these blocks is available to an 
organization, its parent(s) or subsidiaries.

My intention is that if/when the organization comes back to ARIN to grow 
their prefix that they are actively using 80% of the block which was 
allocated under 4.10.1.  So if you have a /24 from 4.10.1 and you are 
using ~205 IP addresses you can expand to the next bit boundary.

My assumption/intention was that ARIN would take the /10 that has been 
reserved under the existing 4.10 policy and divide it into two /11s one 
for 4.10.1 and one /11 for 4.10.2.  Other IANA returned blocks would be 
placed into the 4.10.1 pool.
