You don't need to be a good writer to recognize good writing, the same goes for code.
Okay bit of nuance; this applies to fiction / nonfiction writing based on writing style, not so much correctness - for judging correctness you don't need to be good at writing code (or legalese, or fiction), but you need to understand what's written on the one hand and what the writing should express on the other.
