It's very common IF the Lowrance transducer was providing on plane depth with a Lowrance unit. James is just going into more detail that what you would normally get.
The model of the Y cables in the video are discontinued and are different now.
Currently its the 9 M SIDB Y for the Helix MEGA and 14 M SIDB Y cable for the SOLIX.
