That's an okay metaphor to look at it. However, a basket can be filled, emptied and one basket cannot be the member of two other basket at once.

The one thing where the basket or bag analogy is seemingly helpful is when pondering about whether an empty set can or should exist (and e.g. pic related is not a fan of it), but this also only helps because indeed the basket metaphor is so physical and an empty basket still is something.
