Ack: yes/no/any

can i have explanation for the following:
in one of the rules example the field ack is 2, and represents as "yes" in the second file
in the rest of the exapmels the field ack is 3 and represents as  "any"
BUt in the fw.h file the representation is:
ack no = 1
ack yes = 2
ack any = ack_no | ack yes
So what is 1?

0x01 = no (decimal 1)
0x10 = yes (decimal 2)
0x11 = any (decimal 3)
