NeoKey USB install problem

[Ycore]

Ok, I reopened my PS2 to make sure the single wire link was ok. According to the picture I worked off of at: http://www.modchip.ca/neokey.html version 4 diagram my install is ok. If you'll note the picture indicates that the wire should be soldered to the TOP part of the chip (figure A).

Now if I go to:

The same diagram indicates that it should be soldered to the BOTTOM of the chip.

My question now is which diagram is right, and does it make a difference if it's soldered to the top or bottom (or even middle?) part of the chip?

Thanks in advance, just dis-assembling my PS2 to this extent makes me cringe
