Yeah, Russell O'Connor pointed that difference out and I saw no point in
committing to the hashSequence, so I amended both the paper and the
BIP. The paper will get updated in a few days with the typos people have
found, but I thought that the BIP discussion was more urgent to keep up
to date, so I pushed that directly :-)
