It's not just a rumour, it's "official":
Notably this is a page on the uBR7200 and the same diagram doesn't
appear on the 7200 page, so your suspicions about it being for things
like L2TP termination are probably correct.
Cisco don't have any experience - that I know of - in SMP kernels, so at
least with the current IOS I think a true load-sharing arrangement is
unlikely. What they do have a vast amount of expertise in is distributed
processing, which again ties in with offloading things like L2TP tunnels
to a seperate processor...

I'm just learning new things with the passage of time
