[Mauiusers] nodeaccess policy - does it work on a job by job bases?

According to the maui docs, the node access policy can be overridden on a job-by-job basis using the naccesspolicy (described at the link below). I'm able to submit my job with a singlejob node access policy, but it appears that maui is letting other jobs onto the nodes. Does this feature of maui work?
I have a cluster of 8 nodes with 2 processors each. The jobnodematchpolicy is exactnode, so I get 8 processors on different nodes when I submitting with qsub
qsub -l nodes=8:ppn=1,naccesspolicy=singlejob $myjob
Afterwards I submit another job with
qsub -l nodes=8:ppn=1 $mynextjob
I expect the 2nd job to wait because all 8 nodes are running with a singlejob access policy. Instead this job gets 1 processor per node and starts running right away.
Am I misunderstanding the nodeaccess policy?
