Difference between "di" and "su"

Both of these prepositions mean "about".

So when do you use which?

"Su" is about in a physical sense, exempli gratia, "he was walking about the area", I suppose. "Di" is more of an....abstract sense, and can often be replaced with "of", or "concerning", exempli gratia, "He was thinking about his girlfriend." :3

There's a question in one of the exercises and it goes something like "Loro scrivono su di lei" Mind explaining why both words're used? Thanks in advance :)

I think its like "che cosa", where a couple of different words could be used and are correct, as well using them all is correct. Not totally sure though

Possibly since some meanings of both 'di' and 'su' are not 'about', using them together emphasises that this is the 'about' meaning.
