The router just sent an RA (1304) only 50 msec before getting the RS, and
routers won't reply to an RS immediately if they have sent an RA recently.
You can change this delay with MinDelayBetweenRAs in radvd.conf, but you
really should have a good reason for doing so.

Why? ff02::16 is the well-known address for router discovery...  -Nathan
