It basically just uses the default EncodedNumber.BASE, irrespective of the actual base that was used to encode that particular encrypted number.
See also the problem raised in issue #75: If you run the alternative_base.py example with numbers that have a non-zero exponent, then the addition will produce a wrong result.
