That is not a puzzle:

fmtutil-sys is called via runscript.tlu in Windows.
runscript.tlu is a script for texlua (== luatex).
In luatex, putenv("engine=luatex") is executed.
In Windows, an env var engine is equivalent with ENGINE.



It is really strange that
fmtutil-sys --byfmt pdflatex
and seemingly equivalent

# perl mkfmt.pl
my $cmdl="pdftex -ini   -jobname=pdflatex -progname=pdflatex -translate-file=cp227.tcx *pdflatex.ini <nul";
system($cmdl);

create different format files!!
