What is the purpose of using a "frame delay"? e.g Delay Node with "0" second time

I’m in the middle of watching the anim pose snapshot training video on the UE4 channel.

Using a delay node with “0” seconds was used to delay for a single frame. There was no explanation as to why these single frame delays were neccessary.

I’m a decently competent BP scripter but not super advanced, Can someone explain the purpose of using the Delay nodes for a single frame please?

Thanks!
