Is the author referring to the SRB nozzles?

Yes.

Thanks. The paragraph i quoted does answer the question, but did not do much
to help my understanding of the concept. I was struggling to wrap my head
around of the concept of the SRB nozzles "moving in opposite directions".

Following the replies to my post, it is only now hit me that the the
movement refers to swivelling of the SRB nozzles. Seems to make perfect
sense. I'm sure there is much more to it but at least this is a start

My original searches in Google was along the lines of "Shuttle roll
program", but i've now refined them to "Shuttle SRB steering" and "Shuttle
SRB gimbal" and I've now unearthed a mountain of information catering to
levels of expertise from raw newbie to rocket scientist

Thanks to all who replied.
