Bullhockey. The requirement is that the organization must "be
an LIR" as defined under 2.4. That requires that they be allocated
(not assigned) addresses from any other IR. Typically that's an RIR
like ARIN but there's not restriction on it being another LIR.

If I convince my local ISP to allocate a /24 to me and I assign some
of those addresses to one of my customers, I already qualify for an
IPv6 /32 under 6.5.1. For that matter, I can ask my ISP to allocate a
/48 of IPv6 addresses and qualify for a /32 without ever using any
IPv4 addresses at all.

IPv6 is a total red herring in this discussion.

No, you're right about that. I'll correct and to
specify IPv4. Do you see any other clauses where it needs to specify
that a non-IPv4 allocation or assignment doesn't count?
