As the descent progresses Aldrin calls out cues and vital information while Armstrong looks out the window, you can trace the altitude and velocity throughout the radio transcript. Also note Aldrin calls out horizontal velocity and references the lunar module (LM) shadow, the dust caused from the LM descent engine plume interaction with the lunar surface.
As the LM approaches the surface the rate of descent reduces to almost zero about the time Aldrin note that they are "drifting to the right a little."
