If anything RED will *reduce* oscillations by alleviating retransmit
synchronization.

RED and ECN can be considered independently (although they do work
together quite well). You can see ECN as a way of the network telling
the endpoints "Normally I would have dropped this datagram, but I'll
let you get away with it this time". TCP behavior on reception of an
ECN should be the same as when a datagram is dropped, but without the
latency (and jitter) that is the result of a lost datagram.
