They don't sleep BACKWARDS, they sleep hanging upside down from their feet. They sleep like that because they have no other way to sleep as their wings and small feet do not allow them to construct a den or nest.
Budgies may sleep in the top corner of their cage because it makes them feel safe and secure, mimicking roosting behavior in the wild. They may also prefer sleeping at a higher vantage point to monitor their surroundings and feel more in control. It's a natural behavior for them and nothing to be concerned about as long as they are comfortable and healthy.
