PayPal policy update question

Hi Guys
Today I saw PayPal is going to update it's policy soon. Regarding buyer and seller protection. So, I want you to clarify me about this 2 policy update.

• We are revising the listed exclusions to PayPal’s Purchase Protection and Seller Protection to be globally consistent and to clarify which transactions are eligible for protection.
• We are revising PayPal’s Seller Protection so it does not apply where a merchant ships a physical item or fulfills a purchase order more than two days after being notified by PayPal that the transaction is being disputed, reversed, or is otherwise unauthorized.

If anyone can explain, it would be better for everyone who don't get this.
Thanks

Paypal won't protect sellers who sell any types of digital products. Paypal won't protect sellers who do not verify that transactions are non-fraudulent on their own.
