Question about memory reduction in Dynamic Programming

I was trying to solve 383E - Vowels. Using the technique described here: https://mirror.codeforces.com/blog/entry/45223
I managed to get AC here: 61233188 using regular memory reduction (Reducing one of the dimensions to the size of 2).
I don't understand how it can be reduced to one-dimensional like this: 61233599.
Here is an image to demonstrate my understanding of the dp dependencies in this problem:
