This is different, as sed is the proper name of the program (and just happens to be an acronym as well.) awk, while also being a stream editor, is not "a SED".
Anyway, complaining about redundant use of acronyms is IMO pointless and needlessly prescriptive. Language is a fluid thing.
It's worse in that it's not just redundant but actually conveys the wrong impression of its purpose... a bit like saying "yacc Compiler" or "File fsck".
