This behavior wasn't really introduced with "Save as..." in ML. In Lion, if you rotate a page in the middle of a PDF, then quit and reopen the file hoping to undo the rotate, it will still be rotated. Fortunately, it was someone else's presentation where I first saw this.
Anyhow, ML isn't doing a "save" and "save as..." now; it had already done the "save" part. Apple really should do a better job explaining this, but it's most likely not consistent across all apps. Does XCode even do this now?
It reminds me of the preferences behavior where you make your changes and that's it, rather than requiring you to hit an "OK" or "Apply" button as in Windows.
