we are changing a reduce to reduce right here nad i don't understand why.
I m incline to say don't touche the current transformation code at all, is not a cleanup anymore at that point

I agree.
Touched it and became uneasy but the math is correct and I double checked that there is a test to cover it.
This proves it is all right: https://en.wikipedia.org/wiki/Matrix_multiplication#Associativity

Notice the args order passed to multiplyTransformMatrices

return multiplyTransformMatrices2(matrices);
