What I mean is that it's much easier to physically fold a stripe of toilet paper (one person and a lot of walking) than a huge sheet of paper which needed a team of 20 people to be fold.
And again, it's much more difficult to fold a paper alternating folds length and width-wise than only lenght-wise.
And, she did it several years before the Mythbusters guys, for what it's worth.
Give the girl her due.
