newbie question

Greetings. Perhaps someone could answer a question I have. I notice that when
I run ipstat I see many packets under 'nomatch'. I am wondering what this
means. Why don't some packets "match"? My first two rules are

block in on hme0 all
pass out quick on hme0 from 214.43.22.55/32 to any keep state

doing an ipfstat I see:

bad packets: in 0 out 0
IPv6 packets: in 0 out 0
input packets: blocked 2504 passed 3776441 nomatch 722701 counted 0 short 0
output packets: blocked 0 passed 1635430 nomatch 658899 counted 0 short 0

I would assume that the two rules above would match every packet so where
are these "nomatch" packets coming from?

Thank you in advance for the help.
