Mart Fury License - Regular or Extended?????

Hello everyone! I am considering a purchase of the Mart Fury marketplace theme, however I am finding the difference between regular and extended license to be rather confusing and vague. Vendors in a marketplace are charged a commission from the site owner (market owner) on every sale made. Does this make it an extended license? If so… what is the point of even advertising a regular license…seeing as how the whole business premise behind an online multi vendor market is for the market owner to also make money charging the vendors?

Am I missing something here…???
