Wild guess: I do remember from my earlier biology studies in school about osmosis (I think this is the correct translation - where the water travels in and out of the cell depending on the salt levels inside and outside of the cell) and if this process is happening a bit to fast maybe it could in response split the leaf. Again, wild guess.
I have a similar crack in one of my newer phal, one split is almost down to the middle but i also have another leaf that's vertically splitting (seen from a cross-view angle) - i wonder what may have caused that, might have been a mechanical damage before i got it.

I don't think the rate of water movement will cause damage. When cells shrink due to osmotic pressure, they won't break. no splits.
When cells swell up due to osmotic pressure, they could burst, although this is also not likely as the result was seen in the lab on individual cell basis, and these cells were forced to go beyond unnaturally high pressure.
Your phal cracking or any other plants is most likely due to mechanical damage.
Often when the leaves are bent due to careless handling, the center will split open or split without opening. These turn brownish sooner or later.
Again, this is not the same on the cattleyas I see.
I have cattleyas that show small splits on areas where it cannot have suffered being bent, but rather being scratched almost. no idea what happened there.

I'm not sure if it is good for everyone as it may bring the end of the relationship as well.
Most of my female friends hate the look of lady slipper orchids flower if that gives any idea.
