It's as 3vi1 said. Tori is attacker, then its lighter. Uke is defender, then its heavier. Different forces/mass to make different weight values.

Is that the official response or is it just opinion?

I'd imagine it's official.

Its probobly supposed to be like that..

I have also noticed this.. doesn't bother me.

It's the official response.

Ah ok, that pretty much solves the question.

Even if this would be fixed, it would mess everyone up, people are used to how it is, not to mention it would break all exsisting replays...

yeah i noticed that coz like uke won coz he was 2 more points after the 1st move i was like omfgwtfbbq

Then perhaps the uke/tori should be switched, since the current Tori(attacker) is defending the current position, and the Uke(defender) i attempting to claim the win.
You probably understand what i mean even though it doesn't make sense :/.

They are deliberately made to be different, in order to reduce the amount of draws and double dqs.

I am sure I saw another topic about this somewhere, I will dig it up later, but there is your answer.
