Shared Variables are useful for sharing the data during complex Plug-in development by sharing the data between Plugins registered on both the pre and post events.
Any value stored in the Plug-in context of Pre-event will be available in the Post-event of the Plug-in. This way, we can avoid storing the values in a custom attribute. Certain data validation which needs to be done at post-event can be achieved by passing the value from Pre-event of the Plug-in.
