Does this mean that only those domain sales which are arranged by agreement with Sedo?

Does this mean that regular sales through sedo remain at 10%?

Its a bit unclear and Sedo should clarify what they mean primarily for thickos like me. Some thickos have decent domain portfolios.

15% is just for brokerage services.
