As Ratimov posted link stated. That is for preparation to make you make a mistake if somehow you copy-pasted an address from your history.  If you don't copy-paste an address from your transaction history, then you are safe.

So this is like creating an opportunity for the sender to make a mistake and send the amount to the address that is created specifically for this attack.

So to avoid being a victim of this Address Poisoning Attack,

Make sure you don't copy the address from your transaction history.
