In the "chapter" titled "If smoke source cannot be determined and still persists", that starts with the small letter instruction you both quoted, it also reads in the step by step checklist:
AC BUS 1 can be shed as follows:
- GEN 1 ==> OFF
AC BUS 2 can be shed as follows:
- GEN 1 ==> ON
- [GEN 2 ==> OFF
And in the page that follows that one it is explained how to do to shed both buses at the same time, and it includes swithing land recovery before starting the approach.
Ah yes, I wonder if this is how they read it, your elipsis being the skipped over parts...
AFAIK, the AC busses are taken offline by either pressing the GEN 1 or GEN 2 pushbuttons on the overhead panel to off, or possibly through the ECAM.
The checklist for shedding AC BUS 2 includes this part between your [...] areas:
GEN 1 - ON
So both busses are not shed at the same time.
The part about selecting both GEN 1 and GEN 2 to OFF is the ELEC EMER CONFIG
, which is not indicated UNLESS there is DETECTABLE SMOKE IN THE COCKPIT (see the boxed section) There was none in this case.
If they had read the checklist carefully, they would have had this information. But yes, the situation is not ideal for reading and this should be presented more clearly.
