Follow-up Comment #1, bug #60840 (project groff):
Bug #60820 covers a documentation shortcoming of \v'|...' operation, which
might explain part of this. ("|" in vertical context does not always specify
an absolute position.)
>From your example input file, Heirloom troff produces nearly identical results
for the second page, and notably different results for the first. This
suggests that part of groff's behavior follows historical troff practice, and
part of it may depart from it. (Or possibly Heirloom does. Even with
Tadziu's explanation linked from #60820, I'm at a loss to explain Heirloom's
results here.)
