The answer to "Why did I get it??" is, you are addicted to orchids and the "different" is irresistible.
Now is a good time to repot. You can put it in a pot that is a little larger although it would be OK in that one for another year. The pseudobulb looks fine... I think it will stay nice and fat without water. If you see little ridges on the surface, perhaps a little water once, but no more. Once you see new growth, your resolve will be tested.... it is soooo tempting to start watering. No... wait. Roots do go down into the medium so you can't see how long they are but there are other signs. First, the new leaves should be opened out - so they will be of substantial size by then. Also, after the first group of roots, a second batch will start about the time that the leaves spread out, and you will see them before they plunge into the medium. When you see that second group of roots, it will be time to start watering.
As the new growth matures, it will LOVE your tropical climate.(Even when dormant it needs warmth... the species in the Catasetinae group come from tropical but seasonally dry areas) When it is growing, it will want as much water as you can give it, and and also give it fertilizer (like twice as much as the rest of the orchids, or time-release tyep also good), because it will grow so fast that you can almost see it grow.
