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?

/home/user1 <- is a directory. It has world execute. chmod 750 /home/user1

thank you,but what is 'world execute',is ther anything special? i never heard that,could you expend on that ?

Permissions are divided into user, group, and other (also known as world). Jim is saying you have the executable permission bit for "other" on that directory, permitting anybody who knows the path to cd to that directory (but not necessarily read it).
