Because it is a wrapper for the global qApp pointer. When you create your 
QApplication, qApp gets updated to point to it. In PyQt two different Python 
objects exist - the qApp wrapper and the QApplication wrapper - but they both 
point to the same C++ QApplication instance and can be used interchangeably.

It is safe but it doesn't buy you anything except the saving of one Python 
object.
