Purpose of multsite copier - doesnt seem to be appropriate for my needs

It seems I have misinterpreted the purpose behind this plugin. I have two separate wordpress sites and purchased the Multisite content copier to copy posts between my two websites taking 'multisite' maybe too literally.
It seems obvious now that I cant use this plugin. I purchased this plugin as using the normal export/import features of the Wordpress exporter/importer tools did not allow me to bring over the featured images and I was hoping this plugin would overcome this issue for me.

Hoping you can advise
