Reflexive access-list

Hi all, I'm reading the cisco press ccie routing and switching practice labs by martin duggan and Maurulio gorito. On lab 5, says allow bgp and any other traffic, and here is the config on the book:
ip access-list extended in_filters
 permit tcp an an reflect TCP_Traffic
ip access-list extended out_filters
 permit tcp an an eq bgp
permit pim an an
permit icmp an an
int atm3/0
 ip access-group in_filters in
ip access-group out_filters out
I just wonder why the in access-list only reflect tcp traffic but not others. Should others traffic are implicitly denied? Or, others traffic are just not reflected?

Thanks for any explanation.
