Well, sort of— Hermès is quite strategic with the quantity of items they make available. Instead of clearing stock each season/year, the company creates demand and exclusivity by limiting the amount of bags sold.
Paris sends out bags to stores in batches, and sometimes those batches arrive
much later than expected. Other things that come into play are the size/amount of traffic in your boutique and the desirability of the specific combination you purchased. Certain colours and leathers historically sell slower than others. But simply put, yes, it is very likely that your bag sat in a stock room in Paris for years before arriving to your store.
I bought a Jypsière last year in-store from 2015! Just another one of the mysteries of Hermès.
