I'll be honest, I still don't get it. Either because English isn't my first language, or because I'm a bit slow. Nah, it's got to be the first explanation.
These types of clues are more common in "PandA" crosswords, and I believe that if you split up REIN and place it in the clue you get REstraIN, which also means rein (in)
