Without looking at the product listings in detail, I can tell you that two software download sites from the same people are not likely to get two listings, regardless of whether they actually have the same programs on both.
We would consider those two URLs to be parts of the same site. You may decide for business reasons to spread a single business across multiple domains -- that's your right. We won't even care if you want to break the navigation across your site so that it's difficult to get to all the information starting from a single point. Again, that's your right.
The ODP, however, has a policy of not giving multiple listings just because someone decides to buy multiple domains -- and that decision is within the rights of the ODP. The ODP is neither intended to be an index of a website, nor a substitute for effective website navigation.
