Just going by ARIN's wording:

"Typically, end-users receive IPv6 addresses from an Internet Service 
Provider (ISP), not directly from ARIN. Assigned addresses obtained 
directly from ARIN are the least likely to be globally routable."

Also, the size of the assignment is a /48.  A lot of folks are filtering 
outgoing announcements of anything longer than /32 in many cases to 
enforce aggregation policies.  So in this particular case where global 
reachability for multiple multi-homed sites is a must, it sounds like a 
direct assignment is really not suitable.  Multiple direct assignment /48s 
might get closer to the desired outcome but if the parent organization has 
a lot of sites to deal with then for all intents and purposes it's an LIR 
for its remote sites.
