This prints out 'y'. It's not surprising because what I suppose app.data is doing is just returning a slice of the dynamic array. Clear() resets the counter of current position. But this behavior is confusing in practical use, IMHO.

Should calling clear in your opinion guarantee that a new array gets allocated?

I don't find it confusing at all, what did you expect?
