I think it's self-explained in the FiA transcript when Alonso did it and when Felipe didn't get the information. "The sequence of events" is self-explanatory. It happened when Felipe's lead was disappearing by half a second or more per lap.
I have seen the transcription now, thanks to Watkins, so I can give you a more elaborated answer:
- Massa's largest time difference with Alonso was 3.5 secs on lap 27
- that time difference goes below 3 secs by lap 31, and below 2 secs by lap 38
- the overtaking is in lap 49
- the FIA report says that the fuel mix was turned to saving mode "a few laps" before the overtaking
What we don't know is if "a few laps" before means before lap 31, and therefore helped Alonso close the gap to below 3 secs; or between laps 31 and 38, and therefore helped Alonso to close the gap to below 2 secs; or after lap 38, when Alonso was already less than 2 secs behind Massa.
If it was before lap 31, I fully agree with you that the 3 secs rule did not apply; if it was after lap 38, the rule could have been in place and the fuel-mix game could have started afterwards; if in between, who knows...
Of course, we cannot prove that the 3 secs rule was in place in any of the above situations. And obviously, the difference in fuel mix did help Alonso in those "few laps" his revs were turned up while Massa's weren't.
