This is also the motivation behind rearranging memory access, so that we minimize the number of times we need to copy rows into row buffers.

Row buffer can be thought of as a cache that holds only 2kb, we want to optimize our access pattern so that each time we load bytes we don't have to go through steps 1 and 2 on the previous slide.
