EDIT Everything I mentioned below are taken care of by Lecture 245. 
In the video Sam says that we could end up running both the Chase and Suspicion behaviors if we are not careful with our conditionals. I thought this was impossible, since they are both under a Selector node which means if one of them runs the others should not. Is this correct?
EDIT This condition is required so we can make everything mutually exclusive and also abort tasks as necessary
I believe this will be sorted out in the following videos. Just wanted to share if someone else notices the same problem.
