They can be technically separated, but each private key is assumed to
have one only user.

Thus if you use a key with ID A, then same key with ID B, people can
easily deduce that ID A and ID B are IDs of the same physical personn.

IDs are isolated inside th OpenPGP system, but you do not live in this
system, you live in real world, where people can deduce thing from
different sources.
