Anyway, Maybe what happens is that the reed gets bent (literally) and because it can't spring back to its original position the harp goes flat.
Sorry to disappoint you. What you're talking about is reed offset, or the angle at which the reed diverges from the reedplate. This has nothing to do with pitch, so far as I know.
What reed offset does affect is reed response.
The higher the offset, the bigger the gap between reed and plate. A bigger gap means you can attack the reed much harder, but also that it requires a harder attack to activate.
The lower the offset, the sdmaller the gap. A reed with a low offset will respond to softer playing, but will refuse to speak of attacked too hard.
For overblowing, and for extremely fast playing, the reed offset is generally set low, while for heavier playing, it is set higher. Factory settings tend to be mechanically uniform, and err on the side of being too high. It's worth it to learn to set the action on your harps to suit your personal playing style and desired response.
Much of this is covered in the article on overblowing in soon-to-come-out HIP No. 4.
