While this particular case seems to have been resolved, I'd note that with the churn in the industry, this kind of thing is hella common.
Another example: the Optim line, which IBM quietly sold to UNICOM a few years ago, yet still markets as if it's their own. Obviously that's because of an agreement with UNICOM, but I'd be unsurprised if a savvy prospect couldn't play the two off each other (which is probably why IBM have been so quiet about having sold it).
