This statement as quoted is false. I'm guessing it is a misinterpretation of the policy that employees may work remotely from a different country for up to 14 days per year without approval. The announcement that came out yesterday stated that this policy has been reinstated. It does not apply to domestic WFH.

That sounds like a legal thing. I'd guess some countries will require payroll tax withholding, company registration, etc for longer stays, also possibly depending on whether google has offices there, if you are a dual citizen, or whatever else, so they need to consider them case-by-case.
