That's simply the way the POSIX ACL mapping is designed. Onwers are given read (and for a directory) write access by default. This maps what users expect, that the owner of a file/directory always has access to it. If you want more precise Windows ACL mapping, layer the acl_xattr module on top of the default POSIX ACL mapping, which will present a Windows view of the underlying ACL mapping.
