What is the difference between Call and Branch?

Call

The Call instruction calls another specified activity and executes it. When that activity completes, control returns to the calling activity.

Branch 

Instruction to find another specified activity and branch to it without a return.

When the system executes a Branch step, control transfers to another activity found through rule resolution. Execution of the original activity pauses.

When the branched activity ends, the processing of the current activity also ends.

No steps after the Branch step are executed.
