Forum:Detach and Timing

So, i know that monsters' effects, such as Spiked Sunfish, can be activated when they're detached, but why is that? i thought optional trigger effects, with "If..., then..." effects, were allowed to activate even when something else is happening at the same time like drawing Watapon with Graceful Charity.
