Does it benefit the overall process? Yes. The sequence below maximizes benefit and outcome, under most conditions.
Knowledgeable word care/restoration folk would either strip or clean, then brighten with oxalic acid, then allow to dry. Then sand (40 grit for aggressive removal, 60 for moderate, finish with either 80-100, fairly pointless/counterproductive to go above that for decking without knowing precisely why) and stain.
