I think they were referring to the contradiction of "verbal agreement... especially if it's in writing." But yeah, the snarky comment does not help anybody with anything.
A verbal agreement inherently means there's no written agreement. Also, oral = verbal.
I wonder how that applies to embargoes that don't come with formal NDAs or whatever.
What I'm saying is that a verbal agreement is binding if there's an intention to create binding relations, and not binding if there is not that intention.
Verbal just means using words.

Of course agreements are using words. How they express those words (orally or written) is the difference. Here's are better answers from actual lawyers: https://www.quora.com/What-is-the-difference-between-oral-an... and https://www.quora.com/Is-there-any-difference-between-an-ora...
There exists separate legal dictionaries precisely because words take on new meanings in a legal context. Searching "verbal agreement" brings up numerous legal blogs and sites discussing what you are calling "oral agreements". They are likely interchangeable in a legal context.
