That's exactly why it's there. If the matrix has already been
initialised, then there is not need to re-initialise. This will
typically be useful for nonlinear problems.
If initialising the matrix is requiring 90% of your runtime, you're
probably doing something strange. Initialising the matrix does now take
more time, with the trade-off that assembly is now much faster and less
memory is required.
