[Cbc] solution in CbcEventHandler

Dear All,
I'm using cbc to build a pool of solutions for a MIP problem.
My objective is not only to find the optimal solution, but to find many
different, close to optimal solutions.
Since I want to process every solution found I wrote a specialization of
CbcEventHandler
Looking in cbc examples (driver4.cpp) I noted that after checking for events
solution or heuristicSolution
The event handler calls
model->bestSolution
to get the solution found.
My question is: what if the last solution found by a heuristic is not the
best found so far ???
Would it be better to access the solution pool
(savedSolution[numberSolutions-1]) ?
Thanks in advance,
