multiple update commands

Hi,
I thought to have read that you do not have to send "update" commands separately in a mail. But today I send this:
update 3 @done @archive
update 4 1/2/10
update 6 @done @archive
update 7 @done @archive
update 8 @done @archive
update 9 27/2 9am-1pm
update 10 @done @archive
update 11 @done @archive
and got: items 3, 4, 9 were updated and the rest stayed as it is...
 
indifferent I’m confused about my task list now...
Inappropriate?
