No. ω is angular acceleration (as said in the document). You can also see that I have used M=ω*I which indicates that it is angular acceleration. So the formula is correct.

However, ω is often used to denote angular velocity so you are right that it is confusing. I will change in the document. Thanks for being a careful reader.
