Even after writing scripts for nearly a decade and a half, I still haven't been able to wrap my brain around "a reference to". This script fails:

tell application "Address Book"
set M_List_Group to people of group "Mailing Lists"
set label of email 1 of every item of M_List_Group to "List"
save addressbook
end tell

In this case you are asking for every item of M_List_Group. M_List_group is a list and the result is a list. You will remember that applescript lists do not have an "email" class nor a "label" property. You cannot say:

set label of email 1 of every item of {1, 2, 3} to "List"

However, when you use a reference you are effectively saying :

set label of email 1 of every person of group "mailing lists" of application "address book" to "list"

in this case you are setting the property of a class of an item which is one of a range of items.
