I just dealt with this last week, and the answer is: Yes. WordPress requires a "secondary funding source". They do not say they do, but... they do.
I spent hours on the phone with PayPal, and numerous posts with WordPress. WordPress insisted it was a PayPal issue, and pointed to outdated credit card (nope) or sending limits (nope), PayPal insisted it was a WordPress issue, and after their managers went through hoops to try to get it to work I was sent on to a higher level manager, who said they deal with this regularly, and WordPress requires a secondary funding source.
Adding a secondary funding source, suddenly, no more issues! I was told that WordPress was letting the "Store team" know, so they could work this out with PayPal. Apparently... nothing has changed. But, it has only been a week! :-)
