When I reverse an animation that has ended sometime ago, it also accounts for the time between its end and the moment I begin the reversal!

Hard to make it any clearer in the title, so I explain here:

I have an Animator with a State of about 1 second duration. I have added a speed multiplier parameter on the state. After a while, I set the multiplier to -1.0f to reverse that animation. So far so good.

From the end of the animation state, until I begin its reversal, let's say it's been 5 seconds. When I initiate the reversal, the animation doesn't immediately start playing. Instead it sits idle for another 5 seconds, THEN I see the animation playing in reverse! If I trigger the reversal 2 seconds later, it takes another 2 seconds to actually see the animation reversing, and so on.

It's like the animation is still playing after it ends, so when I reverse it, it reverses through the time it's been finished and idle as well... This is quite weird. Anyone care to shed some light here, I'd really appreciate it!
