On October, I reported this issue to the Wolfram support: [CASE:4323226]. They confirmed the bug and suggested a workaround. Here is the response:

button = Button["Move",
SelectionMove[EvaluationCell[], After, GeneratedCell]];
Print["one"]
Print[button]
Print["two"]
Print["three"]

Alternatively, using a number greater than 1 in the fourth argument of SelectionMove gives the same behavior:
button = Button["Move",

Button["Move",
FrontEndExecute[{
SelectionMove[EvaluationCell[], All, Cell];
SelectionMove[EvaluationNotebook[], All, CellGroup];
SelectionMove[EvaluationNotebook[], After, CellGroup]
}],
