I agree, because the pot size has no actual bearing on how many growths the plant has or how tall the plant is, occasionally this happens.

The larger the pot, the more potting media there is. Potting media retains water (or at least should to some degree or another). The more water that's available as a result of the abundance of potting media and the smaller the root mass in relation to the amount of moisture being held by the media, means the possibility of an over abundance of water is quite high. When there is too much water, the root's ability for gas exchange is limited (the roots have a hard time "breathing"). Thus the cells of the roots suffocate to death. When death occurs on the cellular level, we can't see it without the aid of a microscope and it goes undetected. Because of this, the dead cells start rotting (as it naturally would - dead organisms decay due to bacteria or fungus breaking them down). What we see is the end result of what was briefly described - what we call "root rot".
This is the simplified version.
Basically there needs to be a balance between the water and air available to the orchid's roots in order to avoid the problem of root rot (again, a simplified explanation).
