cursor.atEnd returns true, cursor is at start?

I am clearly doing something stupid that a newbie does, but I can't solve this. Here is my test code:

ui->TextEdit->setPlainText("testing\n");
  QTextCursor cursor( ui->TextEdit->textCursor() );
  cursor.movePosition (QTextCursor::End, QTextCursor::MoveAnchor);
  if(cursor.atEnd())
  {
    ui->TextEdit->insertPlainText("true\n");
  };

ui->TextEdit->setPlainText("testing\n");
  QTextCursor cursor( ui->TextEdit->textCursor() );
  cursor.movePosition (QTextCursor::End, QTextCursor::MoveAnchor);
  if(cursor.atEnd())
  {
    ui->TextEdit->insertPlainText("true\n");
  };

To copy to clipboard, switch view to plain text mode 

This prints:

true
testing

I would expect the lines in different order. What am I missing?

The Qt doc clearly states.

QTextCursor QTextEdit::textCursor () const

Returns a copy of the QTextCursor that represents the currently visible cursor. Note that changes on the returned cursor do not affect QTextEdit's cursor; use setTextCursor() to update the visible cursor.

just use the moveCursor method form QTextEdit

I did read the documentation, but clearly from a wrong place. Besides, you can't always rely on snippets from the Internet, as demonstrated. Thanks for pointers!
