I think the "weight" of the pot, is intended, to help with keeping an Orchid, such as Cattleya, from tipping over, as easily, particularly from wind, ( or being top heavy & you wouldn't want that to happen, while in full bloom ! There was a similar one shown, but somewhat smaller, ( & likely much lighter in weight) with small holes, to ,more easily use as a "hanging planter"., as Ursula suggested.
Cattleya do have a tendency to attach roots to the pot, especially if you planned to keep it outside for summer & the thicker pot retains more moisture, possibly if even from just regular watering & in addition to rain, the humidity & thunderstorms.
Though, when humidity drops, quite the opposite, if in any sun.
While, I've tried similar, with slanted slots for air flow & round holes, before & found they tended to actually dry out, a little too quickly & sucked the moisture, from the long fiber moss, too fast, for my liking & dried rapidly..& that may be a problem , if kept indoors. You can always try it & see how you like it.
