For instance when you change watermark options, both Pdf and Xpz outputs are regenerated. By default the Pdf and Xpz outputs are replaced in cache when watermarks are changed. If you set this property to true, the Pdf and Xpz outputs will not be replaced but all variations will be kept in cache instead. This can be useful especially when you want different outputs for different users. So this way, for instance you can have different watermarked variations for each different user.
