HCS12 DBNE Instruction Timing

I am trying to understand the instruction timing listed in the HCS12 reference manual for the DBNE instruction.  Is this an instruction where 3 cycles are required if the branch is taken and only 1 cycle if the branch is not taken?  "PPP/PPO" would seem to indicate that this is not the case.

 

Thanks for any help someone can provide on this.
