Need help figuring something out

Fold the tubular into a neat bundle for storage beneath the seat or in a bag. For a clean job, open the valve stem and start by holding the tire in two places and pulling it taut so that there are two folds with the valve stem at one. Holding it like this, lay it on a bench and ensure that the basetape is facing up. Carefully, roll the tire over on itself pushing out any air as you go. With a few tries, you’ll roll it up into a neat bundle with symmetrical overlaps. It’ll look so professional, you may decide to simply wrap it in the sports page of the Sunday paper and toe-strap it beneath your seat rather than stuffing it in a sock or bag. That way, your riding chums can admire your handiwork.

Does someone understand this well enough to explain it to me - I am sorry for being thick - but I think it is one of those things that makes obvious sense once you have seen it !

I understand it (what is being said topologically) would you like me to explain ?
