Can someone tell me whether this is correct?

Can someone tell me whether this is correct?

So I ride the wind to my Diana from Rengar to other other battlefield and activated my passive, he said that I can't do that because that the same showdown.

However, I told him that it was different showdown because its on a new battlefield. Shouldn't that other battlefield ended with Rengar conquering, thus allowing me to do Dianas's ability on that new battle field?
