You are both right and wrong, SDS recognises 0+1 as a special case and tries to make it a 1+0 if it can.
Cool, can you tell me where this behavior is documented?
In the Disksuite 4.2 Answerbook: Reference Guide: Metadevices: Mirrors
It doesn't say 1+0 but it does state that:
DiskSuite cannot guarantee that a mirror will be able to tolerate multiple slice failures and continue operating. However, depending on the mirror's configuration, in many instances DiskSuite can handle a multiple-slice failure scenario. As long as multiple slice failures within a mirror do not contain the same logical blocks, the mirror continues to operate. (The submirrors must also be identically constructed.)
