concatenate - serial comma incorrectly used with two items

Per Wikipedia, a serial comma is
a comma placed immediately after the penultimate term... in a series of three or more terms
We would therefore expect that a serial comma would not be placed by concatenate()
when given a sequence of two items, but this is not the case.
Expected:
>>> humanfriendly.text.concatenate(items=["foo", "bar"], serial_comma=True)
'foo and bar'
Actual:
>>> humanfriendly.text.concatenate(items=["foo", "bar"], serial_comma=True)
'foo, and bar'
Workaround:
>>> items = ["foo", "bar"]
>>> humanfriendly.text.concatenate(items=items, serial_comma=len(items) > 2)
'foo and bar'
