keiki's can form on the stem, a flower spike or on a cane. So nothing too unusual.
The definition of a keiki is just baby plant. So this is a baby plant on a mother plant = keiki
Unlike baby plants which develop on flower stems, the ones growing directly from the mother plant are best not removed. Trying to remove a so called basal keiki has a high chance of causing serious damage to one or both plants. So now you'll have a plant with 2 crowns, so in a couple years you can expect spikes from both of them!

Many ancestor species of Phal hybrids do this routinely. You wind up with a big clump of rosettes, each of which can flower at the same time. It becomes a very impressive display. I leave them unless I want to give away a piece of the plant.
