I'm not fond of sequences based on words. In fact, I like them even less than those that depend on the number base. However, I don't think this sequence should be deleted. We are allowing sequences that are based on the "word-representation" of integers, and this is probably one of the most important of that kind.
I did notice that the examples used "and" a lot. My understanding is that "and" is not used to represent integers in U.S. English; it is used to separate the integer from the fraction. So you would say "five hundred sixty-two and seven tenths" for example.
Do we have a procedure for sequences that are wrong but we don't have the correct values? If not, could someone who knows what they're doing please fix it? Barring that, if the choice is really between deleting it and fixing it, I guess I could take my best shot at fixing it.

The sequence is missing "undecillion" (10^36), "vigintillion"
(10^63), "unvigintillion" (10^66) and a whole host of other numbers
that come before "two" in reverse alphabetical order.
Not to mention that we'd have to go throught all the "vigintillion
one", "vigintillion two", ... "viginitillion nine hundred ninety nine
novemdecillion ...", for each "illion" that we're missing.
This sequence should probably be deleted.
