Well, I think you might actually have the wrong end of the stick there.
If you need to divide a single bitcoin between two people instead of just making a new one so that they can have one each, well that is pretty much deflation, and it's likely the value of one bitcoin is higher.
If you endlessly make more of a certain money, then that's effectively inflation, and the value will go down because there's more currency units to go around.
Now the thing is, nether of these things change the amount of value people are trying to store when they get their bitcoin, which is where I think you're coming from.
But one of them generally makes the value they have stored go up, and the other generally makes it go down.
