Not necessarily.  See C13-43.1.1:

When a request for a particular MADHeader:MgmtClass has been redirected 
to another location, that location shall continue to service requests 
for the MADHeader:MgmtClass until either the location becomes inoperable 
for some reason or the requests are redirected again away from that 
location.

Separately from admin or SA controlled redirection, the ib_sa module 
will need to determine when to fail back to the master SM/SA.  I would 
do this based on X number of retries/timeouts.
