asterisk users - Nov 2003 - why does context order make a difference in IAX.CONF

so why does this work properly

[iax-llllll]
type=friend
context=iax-llllll-in
trunk=yes
host=iax2.llllll.com

[iax-tttt]
type=friend
auth=md5
secret=blahblah
context=iax-tttt-in
trunk=yes
host=rx8.tttt.net



and this doesn't

[iax-tttt]
type=friend
auth=md5
secret=blahblah
context=iax-tttt-in
trunk=yes
host=rx8.tttt.net

[iax-llllll]
type=friend
context=iax-llllll-in
trunk=yes
host=iax2.llllll.com


What happens is a call that comes in over IAX-TTTT gets dropped
into the iax-lllll-in  context if iax-tttt is first in  iax.conf
