Moca POE filter, does TA need one on the splitter too?

I am getting a Bolt to go with my premier which is already hooked up and hosting mocha. If I have one of these on the mainline in for POE: GLF-1002 MOCA® INPUT BLOCKING FILTER

Do I need another one on the splitter specifically to the tuning adapter because there is one there already (Lpf-1002 Low Pass Moca Filter) and moca does work through house as well as a couple Ethernet shares.

I don't know if it got put in because we were troubleshooting the TA on initial install, or maybe...
