No, "/" is not relative, it is absolute, because it begins with '/'.
See RFC 1808 (Relative Uniform Resource Locators):

 2.2.  BNF for Relative URLs

 [...]

   URL         = ( absoluteURL | relativeURL ) [ "#" fragment ]

   absoluteURL = generic-RL | ( scheme ":" *( uchar | reserved ) )

   generic-RL  = scheme ":" relativeURL

   relativeURL = net_path | abs_path | rel_path

   net_path    = "//" net_loc [ abs_path ]
   abs_path    = "/"  rel_path
   rel_path    = [ path ] [ ";" params ] [ "?" query ]

(which means that CGI.pm -full is 'net_path', and -absolute is
'abs_path', and -relative is 'rel_path')

 [...]

 4.  Resolving Relative URLs

  [...]

     Step 4: If the embedded URL path is preceded by a slash "/", the
           path is not relative and we skip to Step 7.
