Yes: the condition on there code is unfortunately a tautology: it's always
going to be true.

For example, if side=0, although that fails the first sub-condition, it
succeeds in the other two, and because it uses the boolean 'or' operation,
the condition as a whole is successful.  That's why the condition is always
going to be true.

Consider the difference between boolean 'or' and boolean 'and' instead.
