Sure: “yaht” and “yot” sound virtually the same (at least in American English), only maybe slightly different in the length of the vowel; “folly” and “foley”, on the other hand, sound very different from one another.

Yes, that is my point. "Yot" is pronounced differently (as in "foley") outside of America in a lot of cases.

Except (just to be clear) no native speaker would ever pronounce 'o' in 'yot' and 'foley' the same way.
