If you have left the system in G64 mode, then it will begin the XY move as soon as the Z axis begins to slow down at the end of the move. This is the currently defined behavior. The point on Z where this happens depends on the acceleration defined in the ini file for the Z axis. If you do a G61 first, then it will complete the Z move before the XY starts.
