Yes, it should exactly work like this. When Keycloak see the JWT token 
from your client, which is signed by unknown key (this is based on the 
value of "kid" from the token, which must be unknown to Keycloak), then 
Keycloak will try to download new keys from providerd JWKS URL. Your 
client can support multiple keys there, and Keycloak will then use the 
correct one based on the "kid" value.
