The MFN applies to other SAFEs too. YC will get the "best" price during the priced conversion. If you took other money at a lower SAFE, that would peg the "best" price in the conversion -- and thus, that's what YC's $375k would get.

Thank you for the correction. They mention this at the footnote of the article: “1 The $375,000 is on an uncapped safe with ‘Most Favored Nation’ (MFN) terms. MFN means that this safe will take on the terms of the lowest cap safe (or other most favorable terms) that is issued between the start of the batch and the next equity round. Simply put, we’re giving the company money now but at terms you’ll negotiate with future investors.”
