log4j rootLogger seems to inherit log level of other logger. Why?

I've got a log4J setup in which the root logger is supposed to log ERROR level messages and above to the console and another logger logs everything to syslog.

log4j.properties is:

# Root logger option
log4j.rootLogger=ERROR,R

log4j.appender.R=org.apache.log4j.ConsoleAppender
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d %p %t %c - %m%n

log4j.logger.SGSearch=DEBUG,SGSearch
log4j.appender.SGSearch=org.apache.log4j.net.SyslogAppender
log4j.appender.SGSearch.SyslogHost=localhost
log4j.appender.SGSearch.Facility=LOCAL6
log4j.appender.SGSearch.layout=org.apache.log4j.PatternLayout
log4j.appender.SGSearch.layout.ConversionPattern=[%-5p] %m%n

In code I do

private static final Logger logger = Logger.getLogger("SGSearch");
.
.
.
logger.info("Commencing snapshot index [" + args[1] + " -> " + args[2] + "]");

What is happening is that I get the console logging for all logging levels. What seems to be happening is that the level for SGSearch overrides the level set for the root logger somehow. I can't figure it out.

I have confirmed that Log4J is reading then properties file I think it is, and no other (via the -Dlog4j.debug option)
