Thanks—so there's another layer of encryption over the ever changing (Megolm) key that encrypts the room, if I understand this. Looks like I simplified too much.

Sort of. Just to clerify: the first layer (Olm) provides a secure channel between pairs of devices, used mainly to share Megolm encryption state between them.

The second layer (Megolm) encrypts each sent message once per room, using a ratchet described by session key data. The session key data is shared 1:1 between the appropriate devices (past and future) over Olm.
