Why would they....

construct it this way?

And no,

I wasn’t drunk.
The masons weren’t drunk, at least, it looked like a good job, except for the lean.
The house wasn’t leaning and the chimney was straight.
I wasn’t leaning on anything when I took the pic.

Why would they what, not post the entire question? instead of just a teaser.

To get the chimney to penetrate the roof at the peak instead of downslope.

Or vice-versa… very common in my area.

Thank you. I’ve never encountered one.

Have a good weekend.
