Chapter 06 - 04 Iterators confusing text

[xrmx]

In the for desugaring paragraph (https://rust-exercises.com/100-exercises/06_ticket_management/04_iterators#for-desugaring) it says that for get desugared into a loop but then it says that loop is another looping construct, on top of for and while.. Since for is based on loop using on top looks confusing.
