see the discussion in PPML/arin-announce... my recollection is
something like this happened (paraphrased for the tl/dr crowd):
1) someone wanted more 1918^H^H^Hshared-transition space
2) a policy proposal came to ARIN's PP meeting
3) the policy proposal ran around for a time making friends
4) the proposal passed and the ARIN BoT essentially got a message from
IANA/IESG saying:
   "Hey, before you leap... lookout, perhaps the IETF should weigh in?"
5) an IETF draft was drafted (which later had a baby... so there are 2
versions/parts flying about)
6) the main draft was finalized and sent along to the RFC editor, and
made into a BCP
   <http://www.ietf.org/mail-archive/web/ietf-announce/current/msg09959.html>
7) IANA received this /10 from ARIN
