But what would be the point of wrapping the wipe-up rag around
the roll?

I have no idea . . . it's just that the way it was described (wrapping the
rag around an inside-out roll) results in a mess.

Why would you bring anything contaminated near food?

Ignorance.

Next time you are eating sushi, watch the chef very carefully. I'll bet he
uses the same towel to wipe off the cutting board when switching from one
type of fish to another . . . and wipes his knife on the same towel. Very
common but poor practice.
