I have used the logic as you described many times.  I did a test using 
dclerk 5.0.14 with a result as follows:

fpinvc using fields a2 (Quantity)

if: a2 eq "1"
then: msgbox "Quantity eq 1 @af="<@af
if: a2 co "1"
then: msgbox "Quantity Co 1 @af="<@af

You are right in all cases the value of @af was 1, even if the match was 
on the second or third item.

It did correctly stop on the two items finding only values of 1 for the 
first match and any quantity that contained a 1 for the second.

In situations where you use @wlfa2, sort on a2, use and index built on 
a2, I am sure the @af is correctly set.
