To me, this sentence is about how you receive indications of incipent congestion, the sender can change from using only CE to using CE plus the accurate information -or fall back to using just CE - ultimately it falls back to just detecting congestion (loss,delay). So yes, the CE signal could be regarded as input to SCE. The endpoint behaviour, I think, should fall back to RFC8511. Gorry
