I've eliminated that (see attachment).

I suspect a bug in the old groff version.  A vertical line is put into
the current line buffer, the `partially collected line' (similar to
other output like glyphs).  Such partially collected lines are part of
the current environment.  In your original macros, you've switched to
environment 1, then wrote \L, then .ti (which flushes the partially
collected line of environment 1; this is the left line in the first
run), then returning to the previous vertical position, then \L again,
finally switching back to environment 0 -- without flushing the
partially collected line of environment 1!  Consequently, the right
line is missing on the first page, and only subsequent calls print it.
On the next run of .Pg, you are off by 1 line because the call to .in
starts a new line because there is something in the partially
collected line -- the right vertical line from the last call to .Pg.

The solution is to insert a final .br in environment 1 and using .rt
twice.
