You made a reasonable guess.
I have be wondering about the purpose of EXTH 403 for a while. As far as I can tell it cannot be produced by kindlegen.
The other EXTH types numerically close to it control restrictions related to DRM, so it may be related to that. I surveyed the books I have purchased from Amazon a while ago and about 10% have it set to one, more have it set to zero. I haven't found any consistent difference in capabilities associated with it.
