user directory and wheel group

[Asbel Kiprop]

hello @misc!
Kinda simple question here, but didnt fount any answer.
After fresh install i've created new user, added to 'wheel' group.
But /home/user/ direstory and everything in it has "user:user" owner, but
shouldnt it be like "user:wheel" instead?
sorry for bad english, hope for some help
