If gluster support is enabled and shipped in samba-vfs-modules, which is in main, then this samba-vfs-modules will grow a dependency on gluster-common, which is in universe.

Basically this:

# ldd /usr/lib/x86_64-linux-gnu/samba/vfs/glusterfs.so|grep gluster
 libglusterfs.so.0 => /usr/lib/x86_64-linux-gnu/libglusterfs.so.0 (0x00007f2442bb6000)
# dpkg -S /usr/lib/x86_64-linux-gnu/libglusterfs.so.0
glusterfs-common: /usr/lib/x86_64-linux-gnu/libglusterfs.so.0

A simple way of seeing this is that I should be able to install all packages in main without having to enable the universe pocket.
