xdg_activation: token reuse is not clear

xdg_activation_v1::get_token says the following

Creates an xdg_activation_token_v1 object that will provide the initiating client with a unique token for this activation. This token should be offered to the clients to be activated.

Where the key point is that token passed to clients .

However in reality it seems like that implementations mark the token as no longer valide once the xdg_activation_v1::activate is called.

Should the activate just say that the token will be considered invalid, so the clients instead of creating 1 token and passing to 2 clients, will just create 2 tokens for each client being activated?
