Yes, the first version of the access list would permit TCP traffic (but not UDP, ICMP, etc) and the second version of the access list will permit any IP traffic between those hosts - no port restrictions or anything - wide open for those hosts.
I see one of the hosts is using private addressing and the other public. Is NAT involved? If so, perhaps an rsync initiated by the outside host can't get through the NAT. You should be able to overcome this with a static NAT translation.
Also, are you using encryption for rsync? Perhaps it's using ESP or AHP (ala' IPSec). You may need to explicitly permit those protocols in your ACL as well.
BTW, some older versions of IOS even required ICMP to be explicitly permitted. Newer versions permit ICMP when you permit the IP suite as a whole.
