Because PPS isn't encoded in the loran signal.  The only way you have of
recovering PPS information is to know when the next time of coincidence (TOC)
will occur at your location, and start your 1PPS at that time.  A TOC is when
your master chain's starting pulse happens to occur at an exactly the start of a
UTC second.
