Confusion on the design of anchorage bolts required to resists tension on column base plate

Please focus on highlighted part. This is the example problem from SK Duggal Design of steel structure, where question asked to design a slab base, here he calculated tension force acting on bolt (Fb), as 118.81KN and calculate no. of bolt required as 2. But in fig 11.5 he used only 2 bolts as a whole, but my question is shouldn't one side have 2 bolts to resists the tension and hence 4 bolts in total? Thanks!
