What do the coordinates mean in pane:get_text_from_region(start_x, start_y, end_x, end_y)¶ command?

Why does this command NOT copy anything, when I expect it to copy text from column 10 to column 15 on the first line 0 of the scollback buffer? If I change end_y to 1, I do get a selection, but only from column 10 to the beginning of next line, so the first x is working, but the ending x isnt"

  local beg_x	= 10 -- column 10 of the beginning of selection?
  local beg_y	= 0 -- first row
  local end_x	= 15 -- column 15 of the end of selection
  local end_y	= 0  -- first row
  local txt  	 = pane:get_text_from_region(beg_x, beg_y, end_x, end_y)
  win:copy_to_clipboard(txt)
