Because that is specifically called out that the defender cannot speed tokens at Speed 0. This was also subject to a clarification, which allows Vader to Reroll by spending Tokens if he is at Speed 0, because at that point, he is a the attacker . Not the Defender.

Sloane can cause a token to be spent in in the Modify Dice Step (By the attacker)
Defense Tokens cannot be spent more than once during a single attack. ergo, if you get to the Defender Spends Defense Tokens step, they cannot spend that already spent token...
