Short answer is because antenna size - 60cm and modulation - FEC 5/6 what they are using. On the Wide beam there is no sufficient margin for DTH on the north-east Black Sea coast of the country.... instead of transmitting via Wide beam which is receivable from everywhere.
For fun. This is the only explanation that I have. Usually the satellite operators are doing such operations not public.I don't see what could be the logic to circulate a test beam across Europe like a flashlight...
