I don't really think it's timed, she just gets impatient if you fiddle for a long time. When you get a note correct (centered, red light) just move on to another note. Be sure you aren't being fooled by the sequence because she leans over and it seems reversed. The diagram is right to left from the end (top) of the guitar, and the guitar itself is left to right from the top, after she leans over.
That will be ten Dramoi.
