Why does multiply from the layer menu get rid of the white background of an image?

From Photoshop Help files:

Multiply

Looks at the color information in each channel and multiplies the base color by the blend color. The result color is always a darker color. Multiplying any color with black produces black. Multiplying any color with white leaves the color unchanged. When you’re painting with a color other than black or white, successive strokes with a painting tool produce progressively darker colors. The effect is similar to drawing on the image with multiple magic markers.

In printing terms Multiply is the same as Overprint, as Normal is the same as Knockout. If you had a white object or type overprinting on a colored background, it would not print.
