While what you write is not false: once enrolled, a node can take on the role
of join proxy.
But, it makes it sound like the purpose of enrollment is to become a join
proxy. The purpose of enrollment is to carry out the revenue generating
portion of the network... becoming a join proxy is a burden, it's about
"paying it forward" https://en.wikipedia.org/wiki/Pay_it_forward

Mostly they are two terms for almost the same thing.
Properly implemented, they are indistinguishable from outside.
Internally, a circuit proxy involves two actual sockets, with an application
space loop to copy A->B and B->A. For TCP, there are some complexities if
you chose to implement TCP urgent alerts.
A stateful xxx proxy would be NAT44, occuring at the network rather than
application layer.

I think that this is a bit of a Ines-specific answer.
I'm not sure that making allusions to RFC6550 here is helpful for the general
reader.
Maybe:
The stateful and stateless modes differ in the way that they store
the state required to forward the return packet to the pledge.
Similar to the difference between storing and non_storing Modes of
Operations (MOP) in RPL {{RFC6550}}. In the stateful method, the
return forward state is stored in the join proxy. In the stateless
method, the return forward state is stored in the network.
