It looks like you have two User Home Pages. One at Genealogy.com (the first URL) and one at FamilyTreeMaker.com (the second URL). You can have both and use the same username / password and be able to update them.
The Genealogy.COM, does NOT require the Family Tree Maker program. It will only upload a GEDCOM file Family Tree Maker.
The FamilyTreeMaker.COM User Home Page is normally updated from with Family Tree Maker. Yes, it can be Edited outside of the program.
