It basically means "they are impure and have made too many concessions/strayed from the true path" and is something ultras, especially Hoxhaists who can get up to like a third of a given text just being the word "revisionist" prefixed to every single noun, like to use as a catch-all term for why they're unhappy with an ML party or AES state. Sometimes it's actually cogent, like the Hoxhaist critique of China's foreign policy after Mao, other times it's just sectarian whining from people who want to feel like the most pure and clever special lads with the best theory untainted by praxis.
It's full/literal meaning as used by leftists is just something like "going backwards" either in theory or praxis, but like I said in its normal use is just calling a policy, tendency, party, or state impure.
