I don't think it's actually using PaLM 2. If it is, it's not great, but I heavily doubt it is. The commentary they've made on it could mean many things. One of the possibilities is that they're using the API to PaLM-2 to classify the language and translate it to English if necessary, such that the simpler and non multilingual Bard model can handle it. Obviously this isn't necessarily what is occurring, and it could be just Bard is now palm-2 for some instances for testing, or a full rollout. Ultimately we don't know - because it's not open source, and companies are not great about telling you what they're actually doing.
