Understanding 'Presumption of Accomplice' in IPC - Real World Example

I had a hard time grasping this concept in my Judicial Services Mains preparation, and I know I'm not alone. Textbooks just give us some dry definition, but it's hard to connect it to real life. So, can anyone share a clear example or real-world scenario of how 'presumption of accomplice' works in practice? For instance, let's say we have a case like Rajendra Prasad vs. Rupan Deol Bajaj (1984 SCC 579), where the Supreme Court held that mere presence of accused near the place of crime is not enough to presume him as an accomplice. What does this look like in a real court scenario?
