Given there may be no logic to it, he may just enjoy it.
However, the EFATO issue, is an issue. No where to run I would suggest.
I have been operating a Cub out of 300 metres, and only 15 feet wide, (the farmer misjudged the trimming of his ploughed area), trees either end, which involves slide slipping in. No margin for error, and certainly hones your tail wheel experiences. The strip is home to a Kitfox, and we have been using it, the strip, for 'tight landings'.
This guy would appear highly experienced on type, I have not flown a Luscombe, but he would appear to handle it all pretty well. Certainly understanding neighbours, if it is only marginally louder than the lawnmower
