Anecdotally as well, this extends to other fields besides programming/writing code, though personally I define it as the contrary, i.e. someone that writes "sloppily" (without proper grammar, with typos, etc.) will also work "sloppily", no matter the specific work, paricularly when some "team effort" is needed. I suspect that at the base there is somehow a lack in communication skills and "education", or more generally a lack of respect for otherwise agreed conventions (grammar and spelling when writing) that is corresponding to a same lack of respect for other people or for the specific conventions/rules that apply to the specific work.
