So, architecturally, the 2 address spaces are separate and can implemented that way. It could be desirable to have an EID address out of the 2002::/16 space or a RLOC address out of the 2610:00d0::/32 space. But it may not be needed with such a large address space. For IPv4, life is harder because of the vast install base, so the clear separation is harder to appreciate. But you could have the same address assigned from each namespace.
Suppose a nameserver or some other piece of critical infrastructure is in RLOC space, and an endpoint wants to talk to it. What happens? How does the endpoint's site network, or xTR, tell whether the destination address is an RLOC or an EID if the address spaces overlap?
