This can be bad for several reasons:
1) If the lower level has a timed portal and you used scroll of magic mapping to see the closest stairs, it's possible that you have not yet cleared path to the stairs on upper level.
2) It's safer to retreat upstairs, not downstairs. New level can have dangerous uniques etc.
3) Player is guaranteed to act before any monsters when entering a new level for the first time.
