Bug? ( () == [] ) != ( ().__eq__([]) )

Hello,
The following behaviour seen in 3.2 seems very strange to me:
As expected:
>>> () == []
False
However:
>>> ().__eq__([])
NotImplemented
>>> [].__eq__(())
NotImplemented
And:
>>> bool(NotImplemented)
True
Hence:
>>> bool(().__eq__([]))
True
>>> ( () == [] ) != ( ().__eq__([]) )
True
How/why can this be intended?
Thanks, everybody.
Markus R.
