The physical copy will only get used by one reader (at a time). The ebook is going to be, err, "liberated" more often than not around a dorm?
In all seriousness, this is likely a nudge to a preference they have for how they want to sell this and how you should want to buy it.
They advertise the ebook as having interactive features and more compared to the print version. Shouldn't it be the preferred one?
