Watering overhead is a good thing because it flushes water through the plant and pot. This prevents stagnant water sitting around. If the crown of the plant is beneath the soil level then you run the risk of rot. Not because the water came from above, but because the crown buried gets stale. In the wild some of the helis grow submerged for periods, and they don't rot. The reason is that the water is running and therefore does not go stale. Also, on the tepuis rain waters plants overhead for several hours each day, but the rain is in flow and doesn't sit around.
If you have a plant planted deeply in a peat-based mix then injudicious overhead watering may well do more harm than good, leading to oversodden compost up at the crown level. If you, instead, use LFS based soils and keep the plant above the soggy level then overhead watering is greatly beneficial to the plant, drawing air into the soil and keeping it fresh and actually lessening the chance of rot.
That's my view anyway...
