One of the requirements for roots to survive is adequate oxygen. If regular roots of orchids remain water-logged or really wet for relatively long periods of time, then this can prevent enough oxygen from getting into the roots.
The orchid probably can actually grow in that spongy medium ------- provided the grower knows roughly when to water, and how much water to add. This can actually be tricky to do for growers that haven't yet determined a workable watering schedule for that kind of spongy media.
So growers can choose to use other media for orchids - such as bark, or bark/perlite mix, or bark/charcoal/perlite mix, or scoria. And the growers can also choose to use orchid pots with lots of holes at the bottom of the pot - so that water can drain easily from the pot, and also allows air to move nicely through the media in the pot whenever there is nice air-movement in the growing area.
And the bottom of the orchid pot should be kept free of drained water. This is for regular potting methods.
The orchid stem in your pics is still there. It does have a root that has grown upwards. For this kind of situation - this orchid might need a humidity tub that is kept at a nice comfortable temperature (and maybe a small ---- to cut down on chances of this orchid from drying out ----- to give it some time to grow new roots. If the humidity is too low ----- then this orchid could dry out. And drying out beyond some point will really significantly reduce chance of survival.
