Paul,
I didn't chime in earlier, because you didn't say anything about temperature - but this exact same thing happened to me with a new phal leaf... due to exposure to cold. I had a light table located between a big bay window and the front door of my house. During the summer the placement of the light table was ideal as it received solid morning light and then the light table would augment the waining light in the afternoon. I planned on moving it when the whether got cold (I live in frozen New England), but never got around to it. Well after a few weeks of cold drafts, all of the orchids on the light table began to show signs of suffering. One phal that was particularly affected by the cold had a floppy top leaf that looked exactly like the one in your first picture. All the other environmental factors were relatively stable - so I assumed that it was exposure to cold or fluctuations in temperature that caused the droopy leaf.
I moved the light table to a draftless location and I propped up the droopy leaf using a bamboo skewer on either side to keep it in the proper orientation. After a month or two of stable temps and being wedged in by the two skewers, the leaf returned to a normal position and has lost its former droopy disposition.
I know your orchid is not a phal, but it's still monopodial... so perhaps this anecdote is still relevant.
Good luck!
