While shadows grow on one side of the blind, the good part is the window on the other side will still let in a lot of light.

The shadow, however, will be less distinct because the area being shaded is smaller and the light coming in is dispersed more evenly across the window.

As a result, although someone may notice that the person on the other side of that window is moving around or doing something, they will still be able to see through that window very well.
