Brassavola nodosa growth?

[estación seca]

In August 2015 I got a near blooming size seedling Brassavola nodosa in a small plastic basket. On arrival it had 6 pseudobulbs: five in a row, and one branching off the third bulb back. The secondary breaking pseudobulb was floppy at the base on arrival and soon fell off. The oldest 2 pseudobulbs also got floppy and fell off in the next week.

With all those bulbs softening at the neck and falling off I figured the plant was going to die soon, but it did not. I kept watering and fertilizing it, and began treating with KelpMax monthly. It has grown a lot of new roots. It did not attempt to make another new pseudobulb. The base of the most forward bulb looks OK and I kept expecting a growth bud to swell, but nothing.

Two weeks ago a new growth began forming from the bract scar of the second bulb from the front. The lead bulb is doing nothing.

A second, much smaller seedling, from another vendor, arrived at the same time. It arrived and is still on a sphagnum and cork mount. It has made several new growths over the winter.

Is B. nodosa known for making blind growths? Does it commonly produce growths from the bract scars, rather than the eyes at the base of the pseudobulb? Or is my plant making an effort to grow on when all the normal eyes are dead? Does it normally produce growths continuously if conditions are warm and well-lit?
