Most likely I'm misunderstanding you 
but I wrote: "I have also understood that in a case of a failure in the green hydraulic system the normal braking system ceases to work and the yellow hydraulic system takes over."
One question regarding the following....
No. Normal brake failure is basically a non-issue. Alternate brake takes over, .........
For a complete loss of braking..........
If in both cases the yellow system jumps in..what is the difference between these 2 cases?
Thank you!!
