It is the same location, but a different, harder place of the location.

As example:
You choose the normal mode CDE dungeon (level 35) and go west after leaving the entrace room
You choose the hard mode CDE dungeon (level 50) and go southeast after leaving the entrace room, exploring a different part of the location, meeting different bosses
