Indeed, Michael.

Here is a proposal for a solution:

  for sliding window $w in $seq/stream/event 
    start $s when $s/person = "Anton" and $s/direction = "in"
    only end $e when $e/person = "Barbara" and $e/direction = "in"
  where xs:dateTime($e/@time) - xs:dateTime($s/@time) <
    <warning time="{ $e/@time }">Barbara: Anton arrived 1h ago</warning>

Notice the "sliding" instead of tumbling.
Probably the "where" could also be replaced by a "and" with the "only end"
