What would you have done as R2

[justaref61]

Look at the rules book, page 22, ART. 3 a: The second referee shall assist the first referee by ruling upon situations which are clearly out of the first referee's view.

This gives the R2 quite a lot of leeway in making calls which is why a good pregame meeting is needed in order to agree between R1 and R2 as to what is expected.
