possible bug?

In the API docs it is mentioned that

watch_type:
    "1" = Watch for deposits,
    "2" = Watch for withdrawals,
    "3" = Both.

However when I create the agent using the API, the values "1" and "2" seem to do the opposite (based on the "Edit agent" window and my experiments)


I want to use this for a real world ecommerce site. Is it advisable? Are people losing notifications?
