The layout of your first post isn't great, but from what I see, there is a note at the beginning of the procedure, explaining what you should do in case the yellow pump is not available.
So there are 2 options. 1) the yellow pump works normally --> you apply the procedure during the cockpit preparation (from YELLOW ELEC PUMP pb-sw ... ON) etc.
2) the yellow pump does NOT work normally --> you start from the note. In other words there are now different possibilities to pressurise the yellow system. One of them being starting ENG 2 (look at the black circle, indicating different options)
P.S. Airbus qualified, but not on this one...
