That is exactly how it works, and not just in Vegas.
Vegas 8 is older than Vegas 9. When they wrote Vegas 8, they had no way of knowing what kind of files the future versions, such as Vegas 9, would create. So, Vegas 8 can read its own files and those produced by previous versions. But it cannot read Vegas 9 files because it has no way of understanding them.
Vegas 9, on the other hand, is newer than Vegas 8, so Vegas 9 can read the files created by Vegas 8 (and 7, 6, etc) because its programmers knew what kind of files the older versions could produce.
This is not limited to software. A present day electronics engineer can read schematics created in the 1960s, for example, but a 1960s engineer would be scratching his head if presented with some schematics from 2010 because he would have no way of knowing many of the symbols used in them. Or, a modern day audience can enjoy Shakespeare because we can understand the words he used even though we do not speak that way anymore. But an audience of Shakespeare's day would not understand anything we may produce these days because the language has changed and they have no reference to help them understand it.
It is for the same reasons that Vegas 8 cannot read files produced by Vegas 9. It simply does not know what they mean.
