it allows to having left hand at right, or having the string crossed ...
You throw your diabolo just above your right hand, about the height of your shoulders.
Then, you catch the diabolo in a movement starting from above the diabolo. This movement is a simple round of your right hand starting above the diabolo, then going onto it's right, then down the diabolo. Then the diabolo "falls" into the string.
Your arrive in a position with the right arm on the left, between you and the left arm. If you "uncross" your arms, the string will be crossed.
To come back to the normal position, you should cross again your arms in the same position as previously (so the right arm between you and the left one). Then you throw vertically not to hight the diabolo, and you catch it back normally, the right arm on the right (and the left on the left).
You can do excatly the same trick on the left.
