The packet will contain a dynamic number of remote anchor data. remoteCount tells you how many "remote anchor data" follows the header.

TDoA3 is dynamic and depending of the system setup and setting the number of anchor data available in each anchor is not fixed.

And since there can be extra field added after the packer (LPP packet for instance https://wiki.bitcraze.io/doc:lps:lpp), you need to know how many anchor data are contained in the packet in order to decode it. It cannot be inferred from the length of the packet.
