Sounds to me like he's saying that there are many reasons why the 2% of users that didn't run Javascript might have that situation.
Sounds to me like that means less than 2% actually disabled their Javascript, then.
So the original conclusion is still valid: An insignificant number of users have turned Javascript off.
To be clear: Sites that don't -need- Javascript should provide fallbacks for those who don't want the fancy extras and just want base functionality. A contact form should not require Javascript. Of course, that means that user will have to wait for full page refreshes just to see if their data validates. They've made that choice. Everyone with Javascript on can have instant validation and Ajax submissions and have a better experience.
