What is it with "HELP"

Whowefoolin? You must be fooling yourself because you are wrong. The base umpire in the middle always has tag up responsibilities on R1.

Please find me a single written source that has the PU taking the tag at first base. On the other hand, I could quote the UDP 2-man manual and the Referee baseball guidebook, both of which make it clear that the tag up at first belongs to the BASE umpire.
