Everything you're saying is right, but I'm not seeing what's wrong with step 14. Did they edit it?

> Earth turns once every 23 h 56 min (one sidereal day) about an axis tilted 23.4° (the blue line). That spin gives us day and night; the tilt gives us the seasons.

Nothing in step 14 to me implies s procession of the axis.
