Yes, I understand that, did you read the article? 4-6 week delivery and June delivery orders are preparing for shipment. They need to fill the 4/24-5/8 orders before the LATER orders.
Well, it actually depends on the model. If you ordered model X and have a shipping estimate of 4/24-5/8 and someone with an order for model Y with a shipping estimate of 4-6 weeks gets their order fulfilled first, it means nothing other than there is possibly a greater supply of model Y.
We would all like it on our wrist by Friday, but as stated above, if it ships by 5/8, it is on time.
