Popcorn Ceiling "Border"

One bedroom in the house has a smooth "border" (~3") around the edges of the popcorn ceiling. The other rooms have popcorn from wall to wall. Does this indicate a past problem (leak or ???), or was one guy on the crew expressing his artistic side?
Thanks, Chris

Did someone remove a crown moulding by any chance?

It would be a very simple thing to do. Just spray and use a 3" wide putty knife to remove. Sounds kinda cool.
