I think the current descriptions of sending/receiving address list is somewhat confusing to the user:
These are your Bitcoin addresses for sending payments. Always check the amount and the receiving address before sending coins.
These are your Bitcoin addresses for receiving payments. It is recommended to use a new receiving address for each transaction.
So what is exactly "your" Bitcoin addresses? For example, a confused user might think that he could "fake" the sending address when he is trying to pay another people.
I think this might be improved, for example:
You may send payments to these known Bitcoin addresses. Always check the amount and the receiving address before sending coins.
These Bitcoin addresses are yours, you may use them to receive payments. It is recommended to use a new receiving address for each transaction.
