[exim] Ratelimit - same key - different rates?

Just checking to see if I understand how this works.

Suppose I have 2 ACLs referencing the same key. The first ACL has a rate
limit of 1 / 5m / strict. The second ACL has a setting of 1 / 20s /
strict. Does that mean that the data from the first ACL is remembered
for 5 minutes and the data from the second ACL is remembered for 20 seconds?
