maybe because of the forest that part of the coast is not guarded by Big Mom so the only way to go unnoticed would be for pudding to meet with them once they arrived and then use her knowledge to guide them through the forest. in which case she would have wanted the SH to stay at the coast and she would check like once a day or something for them.
