Answer
The pipe would contain the instructions B1B0 (being executed), 5002, and perhaps even B0AA. If the value in register 1 is equal to the value in register 0, the jump to location B0 is executed, and the effort already expended on the instructions in the pipe is wasted. On the other hand, no time is wasted because the effort expended on these instructions did not require extra time.
