If the very short clip I saw is the one you are quoting, the speaker is African-American and that sometimes changes things. I'm sure you are aware of AAVE and other forms of American English outside of standard school "book learning". In the case of AAVE, there is no sharp dividing line -- there's a spectrum. Some African-American speakers speak fully textbook standard American English, some use limited aspects of AAVE, and some use much more. It depends on the speaker and the situation. Of course, that's true for other regional/social varieties of American English as well.
