How should we understand the advantage of fixed-bed reactors in achieving high selectivity when the reaction is accompanied by sequential side reactions? selectivity

Advantages of fixed-bed reactors: (1) Low backmixing, allowing effective contact between the fluid and the catalyst; this enables higher selectivity when the reaction is accompanied by sequential side reactions. How should this sentence be understood?
The occurrence of sequential reactions is controlled by regulating the residence time of the material in the bed layer, thereby achieving higher selectivity.
