The identical "aliasing" happens with CFA cameras having AA filters, they just blur the twists and you don't see the multiple railings above Nyquist, you see mush.

It's not false detail at all until you get to the theoretical Nyquist limits. There is a very large area between the AA cut-off for the EOS 50D, for example and any "false detail" from the SD1. Within this area is very real detail, not false detail.
