I love those door limits. You open the door at 35 knots. The winds increase to 50 kts. Oh well, can't close it. Now.....what do you do when the wind increases above the upper limit. We ran into this at Manchester a couple years ago. We chose to close it and live with it...no problem.
The door limits are similar to the gear limits WhaleDriver.
You can drop the landing gear on your jet at 270, but once extended, can then accelerate back up to 310 or so. The limitation is the gear doors being in transit.
Similarly, on the cargo doors, they are stronger when they are "on the locks" than when in transit and hanging on the actuators. Thus the slower limits for operation as opposed to left open.
