i dont remmeber that part in the song..and dont own that one either :(
...
but, i've seen some people
(i cant do it.) but it's pretty cool...
i've seen them slide their fretting hand up the neck
while their picking hand crosses over top and
starts sliding up from the nut back up to the bridge..

like a slide after a slide?
i think they use their pick, but thier fingers work
just as well?

i hope someone knows what im talkin about
and can explain it better
