Peppermint Wide Legs Pants - side seam ?

Just finished and the fit is real, real good. So good I want to think of them as my kinda sloper. But the location of the side seams is bugging me. They are further back than where I've thought my side seam would be.

They are a bit more than 1 inch further back than halfway from center front to center back. The back section is much smaller across than the front. I've triple checked the pattern - had it printed at a shop and checked the scale. And checking online photos - this seems to be intentional.

Is this normal for some patterns? (I didn't do the fly zipper - just a regular zipper install - with the center front seam allowances meeting).

I love this pattern so am working to sort this one thing out.

Thanks for reading.
