Non-conditional conditionals

Certain warnings/threats with and and not .or convey a message very similar in meaning to conditional utterances, though they are not conditional constructions:
Come home so late home again and Ill ground you for a month.
Dont come home so late home again or Ill ground you for a month.
The meaning of these is similar to the conditional contruction:
If you come home so late home again, Ill ground you for a month
