Hmm... I'm reading the same document and came to the opposite conclusion. :( My understanding is that if all the nodes have the same attribute, then _all_ shards will be deployed among them. As soon as a node with different attribute arrives, that's when the "replica will not be deployed to nodes with the same attribute as that of primary" apply. In my case, I only have one node, hence one attribute available. So all shards should be deployed.
