What is the purpose of these constrains?
I am not understanding why I need to use this constrain. Why do we only use them for the left and bottom side?

Constrains are used depending on the design of your UI, some objects may need more constrains, depending on the location of the object in reference to the view and the objects around it. In this case he only added these two contains because those were the only required ones for this particular design.
In future courses if you are following the track, you will find that he goes into a deeper explanation on constrains.
