Atmospheric pressure in the case of a barometer is when the reading of the mercury height on the tube reads 760 mm. Inside the tube the atmospheric pressure at the reservoir supports the arrangement, thus sustaining P at the 760 mm point. It essentially pushes up the mercury to that height. Hence the pressure at the reservoir would be the heaviest, whereas the pressure at the top would be the lowest.
