Comment (by wpmuguru):

 There were versions of MU which updated the user capability to an empty
 array instead of removing the capability. When a user signed up as a user,
 they were automatically added to the main site/blog.

 I think in the above versions the user was added with no role but the
 security required that they have a capability role so they could access
 the dashboard to change their password, etc.

 Those empty array rows could safely be removed from a core code
 perspective because the capability row is no longer required. The main
 concern would be to ensure the update function is still successful in
 larger installs.
