If the facts are in your head, you can make a connection between them. If they are in different places on the web, unless someone else already linked them for you, they remain separate.
Anki is used a lot in medical education. There's a lot of small details, and you can string them along to form the big picture. An example is going from symptoms -> diagnosis -> treatment options -> drug side effects. You can't just memorize use drug X for Y, but you incorporate information that you know to formulate the best plan. Suppose the patient has kidney disease - you've memorized X is nephrotoxic so you find another treatment.
I will say this is easier for some and harder for others. I've noticed some people have a lot of difficulty recalling facts without a specific cue when using Anki. It's best used with traditional learning, but you can focus more on the why.
