Shouldn't Science Writers Know Something About Science?

I think the author of this article should go back to grade school and retake some basic science classes.

What in my post are you disputing?

Nothing... but since you ask... look at your animation... same if the sun rotate around the center of mass, in some way, the planet seam to rotate around the sun and not the reverse... in fact, planet and star don't rotate at the same speed... change the speed of the planet and it will explain the season...

Notice your illustration doesn't show the movement of the sun.. and assumes the sun is stationary.

Not really... the sun rotate around the marked point on the center of mass curve... by example, for 1945, the center of the sun rotate around the point marked "1945"... you need to see the curve "center of mass" like a extra dimension called "time"... well, if someday i have enough free time, i will maybe make a 3D animation of it...

and here is where thoumsins illustration becomes pertinent. The center of mass isn't always in the Sun and many times its outside of it. Although it always is very close (astronomically speaking) to it

Mainly append when both of the massive planet ( jupiter and saturn ) align in their perihelion orbit ( more near the sun in a elliptical orbit )
