Years ago they did a reorg and moved all infrastructure services under Cloud even though they are not Cloud products. That would enable this kind of obfuscation because Cloud is literally responsible for both Cloud Spanner and non-Cloud Spanner and they can conflate these two in their marketing copy. They probably feel justified in doing so because they share so much code.
