Is there an traveling exemption in the last four minutes of play if you are losing?

Both Kobe and that furry guy walked. Kobe did it twice going to the hole and the furry guy actually took 4 steps on a breakaway. The Furry guy one was so obvious my 8yo called it. She then went and counted four steps on the replay twice. I let her do it because I like to reinforce math skills and as it turned out she was right.
