Problem about Fedora directory permission,can anyone help me?

In fedora,I have two ordinary user named user1&user2 in different
groups,when I logined user1 and created a dir named test/ in '/home/
user1/',and do 'chmod 750 test',so when 'ls -l',it appears 'drwxr-
x---' for 'test',but when I logined user2,I still can enter the dir '/
home/user1/test',it seems stranger ,what problem may it have? Can
anyone help me?
