An editor revised a sentence in my essay as follows. I don't quite understand why he revised it this way. Originally "Distinctive from" was used as an opening adjectival phrase, but it was then amended to "As distinct from" that seems not grammatical as an opening adjectival phrase? (Because this kind of phrase should start with an adjective directly, instead of the word "as"?). Thanks!
Original sentence: Distinctive from traditional deceptions, phishing is characterised by the following aspects.
Revised version: As distinct from traditional deceptions, phishing is characterised by the following aspects.
