One Formidable Form is one “dataset”. The sentence “Map 2nd Dataset” refers to mapping a 2nd dataset to the same PDF form at the same time as the 1st dataset.
For example, if you have one PDF form called “OrderForm.pdf” and you have two Formdiable Forms that are collecting the data that needs to merge into the one PDF form you would select “Map 2nd Dataset”.
If you simply need three different Formidable Forms to map to one or more PDFs, but not at the same time, then you would need the 1-Site | 10-Forms version of PRO2PDF.
