Spotting Directions

I have the spotting down pat but I just don;t understand why my main characters end up being behind them ?
So it’s in a club and I have back ground people dancing
My main group walks from zone 1 to zone 2
In zone 1 they are in front of the people dancing but in zone 2 they are behind them
It looks like the background people are standing on their heads.
Please help !
