Can an attacker be a blocker during one action of playing the ball?

[OmniSpiker]

In this if an attacker was attacking close to net and ball goes into a block, the blocked ball that comes back and hits attacker while attacker is still reaching above top of net would also qualify as a block action.

Can an attacker be a blocker during one action of playing the ball in such a scenario?

Thanks,

I'd forgot to really clarify that the attacker, completes attack. Ball goes into opponent's legal block. The blocked ball rebounds back and hits attacker in the same jump while attacker is still reaching above top of net after completed attack. Just so there's no questioning of separate blocking action after completed attack.
