The issue (i think) is that the animation is done post-rasterizing. So a translate of integer pixels is fine, but scale? Skew? Suddenly you have really visible colour fringing appearing out of nowhere.
The article is talking about "rerasterize the glyphs in their new location", which means it's rasterizing post animation. I think he's implying that there is something unstable with his each pixel is treated that breaks the illusion.
