Bitsharescan question

[DavidColy]

Hindi sigurado kung paano tutulungan ako? Tungkol sa kaalaman na hinahanap ko, patuloy kong ibinabahagi ang impormasyong ito.

Hi folks,
Can someone please tell me what the column headings mean when using bitsharescan?  Specifically the columns Asset Value and Total, which follow Description.

When Description says "account name paid"; Asset Value says 1 OPEN.BTC; and Total says 4000 USD, it seems to me that this means that the account holder sold 1 OPEN.BTC for $4000.

In fact, it appears as though it means the account holder bought 1 OPEN.BTC for $4000. 

Can someone please a) clarify which is the case; and b) let me know if this is always the case or if it depends somehow on the individual transaction?

Thanks
