Correct, you do need the manages block to differentiate them. The advantage is that it allows you to describe things without having to invent new concepts. Assuming `X` points to `Y` via `hydra:collection`, manages can be used to express that 
 * all entries in `Y` are of a specific type:
    `"manages": { "property": "rdf:type", "object": "schema:Event" }`
 * all entries in `Y`stand in a specific relationship with `X`: 
    `"manages": { "subject": "X", "property": "schema:knows" }`
 * all entries in `Y` have a a specific property set to a specific value:
    `"manages": { "property": "schema:gender", "object": "schema:Female" }`

We can even allow multiple of them at the same time, so we would be able to express that there's a collection which manages entities of type `schema:Person`, that `X` `schema:knowns` and have `schema:gender``schema:Female`; in other words a collection containing `X`'s female acquaintances. That's pretty powerful.

Is that concern here actually that it looks more complex/is more verbose or that it has weaker semantics? I can agree with the former but don't think the latter is true.

My concern is that this looks verbose and complicated. Especially that this structure addresses a RDF-specific problem. But, I don't have any more comments. Thank you for your patience :D
