"Note that one feature the MFA flow does not have is individual timeouts. For various reasons, it was not practical to maintain an activity timeout on the individual results within the MFA flow, and so that check is not done. Using a shorter lifetime generally will compensate for that.
On the other hand, the overall MFA result that contains all of the individual results does have the normal lifetime/timeout policy the IdP supports. You can still time out any memory of any of the results, just not at a fine-grained level."
