The pic showing flowers is of T. brachiata aka T.phillipinensis var brachiata - (not my plant) . Note that it is flowering from a lot of nodes all at once. This is very unusual in vandaceous plants - usually they flower from the latest -highest on the stem - "ripe" node - but this species ( under different names) is often seen in pictures like this, and I have seen it on sale like this too.
The other pics are of my young plant ( bought 6 months ago) , now starting a spike (?) quite low down. In fact above it, several nodes look as though they have flowered in the past.
The question is , do they repeat flower from the same nodes ? ( a few things in tribe Vandaea do - e.g. Aerangis jacksonii - but not many. ) Logic says that this must be the explanation for this appearance of multiple flowers. If not the plant grows so fast as to produce all of that length of stem actually bearing flowers in a single growing season - quite an achievement ( the weeds in my cabbage patch grow that fast, but orchids ? no ...)
The odd thing is that no-one mentions this , in all the references I can find in books and on the 'net. Yet it is such a valuable "property" that if the writers knew about this why did they not mention it ? In the other case I mention above - Aerangis jacksonii - it does get mentioned.
So - question - what is the right explanation
