If closed captioning is turned on for the video, when the speaker says "274(e)(4)" the closed captioning shows "274E4" which clearly is incorrect. Because the closed captioning lacks the ability to understand Internal Revenue Code section structures, it simply repeats what it hears. And in doing so, it generates an incorrect text.
I explained to reader Morris that when we are discussing section 274(e)(4) we indeed say, "274e4" or, if you prefer the uppercase, "274E4." But that is not what we write when we are writing about that provision. Indeed, when I taught the introduction to federal taxation course, in the early weeks of the semester I would make it a point to say "section 274 open parentheses e close parentheses open parentheses 4 close parentheses." When I began using Powerpoint slides, having "274(e)(4)" visible to the students while I emphasized the need for precision in writing statutory provisions, it became much easier to get the point across to the students.
The creator of the video and the speaker, who may be the same person, is not at fault for the appearance of "274E4" on the screen when closed captioning is turned on for the video. It's a flaw that demonstrates why artificial intelligence still has a long way to go.
But the speaker in the video is at fault for something reader Morris didn't mention and that I noticed only after watching the video twice. The speaker refers to "IRS Code 274(e)(4)." As I pointed out in Is Tax Ignorance Contagious?, "First, there is no such thing as an IRS code. There is an Internal Revenue Service. There is an Internal Revenue Code. The IRS does not create nor does it own the Internal Revenue Code." Apparently, not enough people read MauledAgain, because the error continues to be repeated. Fifteen years after pointing out the non-existence of the "IRS Code," I had to address the use of "IRS tax code." I did so in Tax Season Brings Out a Question (Which I Try to Answer), But It Also Brings Misinformation, in which I explained that "another problem is the use of the phrase “IRS tax code.” Why? Because there is no such thing. There is an “Internal Revenue Code” for which the acronym is IRC. The acronym for the Internal Revenue Service is IRS. Yes, there is only a one-letter difference between the two acronyms but precision matters. For those interested in my previous reactions to the use of the oxymoronic phrase, “IRS Code,” see Is Tax Ignorance Contagious? * * *."
Precision matters. And when it matters, failure to be precise can be annoying. It can be troublesome. And it can be catastrophic. It's best to get into the habit of being precise when the imprecision is merely annoying so that when the time comes when the lack of precision can be catastrophic adherence to precision is guaranteed.
