Fireworks does indeed support layers in a PNG format - rather like a psd format file. In fact PNG with layers is the main save format for Fireworks documents.
BUT it can also save out png with no layers - it is a simple export option and one which makes developing very easy.
Why does having layers help? I have developed many CD-ROMs where clients make numerous small and large changes to say a word or a background image.
Using png's with layers means that whilst programming in something like Director the developer can simply open up the png (double clicking on that image inside Director) and edit the layers (inside Director using Fireworks), swap things around, and close it down again without having to leave the development environment. This makes changes and smends to work very very easy.
