These red lines are showing the helix moves. As much are these are cutting moves they are shown differently. You need to helix to enter the enclosed pockets and helix is the default method. 

Helixing is inefficient but a necessary method of entering a enclosed pocket. That's the main reason why the moves have such a small step down (Ramp angle) is to compensate for this.
