Scaling along y in 'Affine Transformations' not right?

[rduivenvoorde]

Hi, not 100% sure, in but the second animation (scaling along y) in the section about 'Affine Transformations'

https://www.algorithm-archive.org/contents/affine_transformations/affine_transformations.html

I could not see the difference with the one about 'scaling along x'... both seem to change the upper left element of the matrix:

Then in the the video:

you see the same steps, but then the lower right corner element of the matrix is used to change the scaling of y

Is it possible that the first mentioned animation is wrong?

Thanks! I'll fix this in a few hours! Not quite sure how that happened...
