What this video covers
Reduced motion is honouring a user's request to cut animation. Movement on screen makes some people dizzy, nauseous or worse; the prefers-reduced-motion setting is them asking you to keep things still, and a good interface listens.
With motion on, the panel flew in - lively for some, genuinely sickening for others. Switch to reduced and it simply appears, losing nothing that mattered. This page already checks your own system setting and quietens itself if you have asked it to.
