My apologies, too. I've been short on sleep for a while so I most likely misread and overreacted. I usually try not to do that but, as you can see, am not always successful. Sorry!
The reason the EPS preview file is necessary is that Writer, as a word processor, is unable to render the PostScript data of the image file itself. It can, however, display other image formats because it doesn't need to "print" them onscreen, which PostScript rendering requires. Writer is an editor, not a printer, so it would have to send EPS through a print process and back to the screen in order to display the image. You'll find that Word works the same way, actually, for the same reasons. Graphics applications may or may not be able to render PostScript data directly... often they, too, require a preview.

This seems very strange to me for two reasons: PDF is a printing process, so what comes out through a physical printer should also come out in a PDF, and EPS is a PostScript format. So is PDF. By all rights, the PDF should be correctly rendering the EPS data, not depending on the preview file.
The preview format itself can vary. Usually, if a preview exists, it's a TIFF, but sometimes it's WMF. The preview itself can be included in different ways in the PostScript data, and not every program will interpret it the same way. In short, EPS is not a universal format and is not universally portable. Whether and how the preview file is created, and how it's included with the PostScript, depends on the creator and the settings used at creation time. You might need to either mandate requirements for the EPS files when they are created, or request a different format altogether.
The format differences can go beyond how previews are handled. Do you know what program(s) generated the EPS files? Some applications can (and do) create their own "flavor" of different graphic file formats. Just as an example, the GIF you'd get from PhotoShop may not be the same as the GIF you'd get from, say, the GIMP. They sometimes put different data in the file header, which isn't always interpreted correctly by every program that processes the "universal" GIF format.
What happens if you use a different PDF generator than the one built in to OOo?
CutePDF and
