mistakes of negative inversions?

[Tdol]

! people don't use inversions a great deal in casual speech.
2 When they do use them, they tend to get them right, especially because those who use them tend to be the sort who know how to use them.

Am I right that these are ungrammatical?
`
* "She not just sang, she also danced." (ungrammatical)
* "John not just finished all the work ..." (ungrammatical)

Please, did you mean "not that often"?

It means the same.

Those sentences don't strike me as ungrammatical.
