[Fpga-synth] ISE .syr Question

I think I know the answer, but I need to ask...  I'm working on a project
that uses one shared dedicated multiplier.  Looking at the .syr file, I see
this:

Synthesizing (advanced) Unit <phLUTe>.
        Found pipelined multiplier on signal <P>:
                - 1 pipeline level(s) found in a register on signal <A>.
                Pushing register(s) into the multiplier macro.

                - 1 pipeline level(s) found in a register on signal <B>.
                Pushing register(s) into the multiplier macro.

Does this mean that the design will use the registers that are associated
with the dedicated multipliers and not slice flipflops?

Thanks.
