Lists are supposed to be true when not empty, so both x and y are considered true. Their contents don't matter.
Because both x and y are not empty, x and y simply return the second list object only if x was empty would it be returned [] instead.
Example
x = []
y = [1,2,3]
x and y -----> []
x = [1,2,3]
y = [0,0,0]
x and y -----> [0,0,0]
