spectating a good ET player who aimbots

Today I was playing a match on a german server, campaign, in fueldump.
This allies guy started to make a mess of kills, I myself playing axis
encountered him many times and no matter if I started firing before,
he always got me knocked out, as he did with anyone else, and there
wereonly a apir of beginners, the others all played well.
So I started spectating this guy. He switched to axis at the start of
a new map because all others axis were gone.
I spectated him for more than 5 minutes, and he missed two bullets
only, defending all the bridge and foot-bridge area on his own,
against 3 allies. They simply appeared and felt dead continuosly. Two
misses and no more, with a sniper rifle, killing some like 3 allies
per 20 times or more. The majority of the kills were one body shot and
one headshot, some were single headshots but few.
Looking at his aiming, I noticed that he was nearly *never* on the
target, and I didn't notice a movement when he fired because he was
always moving, almost all of his shots were on the fly. But when he
fired his bullets were always straigth to the terget.
The fact that I almost never saw his aim on the target while he was
firing, could this fact be due to the lagbetween my PC; the game
server and his PC? Or is it due to he using an aimbot, an aimbot which
does "aim - shoot - move back to previous heading" all in an instant?
Just curious, I know it could just be a very good playere, but he
could also be an average player with a bot.
