While it is not specifically stated, a rejected takeoff should be conducted for any caution that you receive while above 100 knots during takeoff.
Cautions such as "Flex temperature not set" should have been addressed in the low speed regime.
The difference between the 330 and 320 RTO discussion in FCOM (not being one to fly the 330 myself) might be due to the 330 being designed and built later and therefore possibly missing out on some of the "franglish" translations that went somewhat awry on the 320.
There are quite a few "franglish" misinterpretations that have never been addressed in the FCOM, however the whole point of the inhibition phase is that if you cannot see it at that time then it is not considered a priority in regards safety of flight.
Hope that helps.
