It is true. In the US if a person is a new client to Hermes, they are limited to one Birkin purchase per year. Once you have established yourself as an Hermes client, most times meaning that you are interested in more of the Hermes products than just the Birkin, then you are allowed to purchase more than one Birkin per year. This is a company wide policy for the US Hermes Boutiques. Whether or not every H Boutique abides by the policy is due to the management and enforcement of the policy.
