No, it doesn't, but your question was "However, what should be the 
advantage of gksudo over sudo?". And the link and quote I posted should 
give an answer.

Well, I'd say it requires both because otherwise you're not doing 
anything as root, but that might be a bit too petty.

Anyway, to show the problem of running "sudo whateverGUIapplication" I 
made an experiment. With a Kubuntu 14.04 live session (on my USB stick 
there is no other *Ubuntu flavour, sorry) I installed gedit. Then I run 
the command

sudo gedit

and I changed some gedit preferences. Then I quit gedit and run the 
command

sudo kate

and again I changed some kate preferences.  Then I quit kate and run the 
command

sudo find -user root

which should return nothing if using sudo with a graphical application 
was OK. However the output was this:

Applications that want to use any of those files / folders, which are 
now owned by root, may no longer work correctly if run as a normal user.
