hand positioning

[shred me good]

while flicking through some all to brief satriani legato tips one kinda stumped me.
"try to keep the palm of your frethand paralell to and almost touching the guitars neck binding"

the only way that i can interpret this ends up with your plalm perpendicular to the fret board. and this seems imposible... how do you play the e and a strings??

so either i have taken this tip the wrong way or, um, or somthing...
could anyone help me out hear, i could barley sleep last night in puzeling!!!

cheers
guy
