Noticed it a couple times today. Passed through cop and the arrows were still alerting forward for several seconds then finally went to the rear . Running the latest version with jbv1.

Right as you're passing a radar source the difference in signal strength measured by the front and rear antennas becomes very slight, making it hard for the detector to tell for sure where it's coming from. Rather than flicker wildly back and forth the V1 waits to make a call on a direction swap until it can be pretty sure about the change. The result is that it may still indicate the bogey is in front of you until a few seconds after you've passed.

The arrows are really useful for indicating the source far enough ahead of or behind you that you can decide how to respond. If you're still speeding and looking for the cop while you pass him then I'm afraid you're on your own.

Or if a cop is behind you but you are approaching large traffic sign above the highway, V1 will show signal in front due to reflections of this sign.
Nothing to worry about.

Radar is susceptible to reflections. Even the mighty V1 can have a tough time deciphering between a strong reflection and the real source.

you also have to keep in mind obstructions of the rear antenna seats & people that could cause a reduction in seeing from behind.

As an example, I passed a cop using forward facing C/O, I was following a bus about 100 metres ahead and for the next 1000 metres or so the V1 was alternating between front and rear arrows due to the strong reflections from the bus.

It was latched on to forward arrows for several seconds after I visually passed the cop then decided to switch to the rear. There were no vehicles in front of me, it felt like cpu lag.

The other replies are spot-on as to the 'why'. But like any other tool, with continued use, you know it so well that it becomes second nature to know what's going on.

I consider the arrows more like using "Kentucky windage" rather than a scope. ;-)
