Exactly. Regarding "everything we improved there or modified, we submitted back as open source", unfortunately the GPL doesn't let you redistribute code after modifying it while only releasing the modifications. I guess "we will release the app you saw as well" may mean that they'd open source the whole app and thus be compliant, but it's unclear. Also the fact that the company was once also known as "Wixpress" is easy to verify [1], not sure why he would contest that.
