I am not able to get that configuration to work either.

The documentation says

"Only one authentication packet is sent, regardless of how many valid keys
exist. The software examines the key numbers in order from lowest to
highest, and uses the first valid key it encounters".

>From that I take it to mean an interface will only use one authenticaiton
string at a time, and depending on which one authenticates first, the second
one will not get in.
