Because Python doesn't do element-wise vector operations like that. The way the normal and operator works is, if the first operand has a "true" value, then the result is the second value. Your first list is not empty, so it's true, so it returned the entire second list.

The numpy module does element-wise operations like that, but not straight Python.
