I am a little confused about the box size import field. It says length, width, height but isn't length and width the same thing?

Say If I have a rectangular such as the one I have in the picture, I assume the dimension coordinates are as follows:

X = Length

Y = Height

Z = Depth

Is my interpretation of this correct? Is the CS Cart KB incorrect by using Length and Width?

Length seems like an ambiguous term, but is always defined as the LONGEST side, so therefore Width is the other side, and Height should be obvious.
