In the first recap, you were hit by 3 Vicious Death procs totalling 44,958 damage. In the second, it was 5 procs totalling 45,339 damage.
The number in the first column of the death recap indicates the number of hits and the 3rd column is the total damage from all of the hits.
As a reminder, Vicious Death procs occur when the killing blow on a player is by another player who has the 5 pieces Vicious Death set bonus active. So a single bomber can result in multiple vd procs for every player they kill -- except when the killing blow is a vd proc.
The death recap is notoriously bad creating false impressions about how a player died. For proper analysis, it's essential to run a proper combat log that has a time stamped line [in ms] for each combat event.
