In file lnodelib.c function get_write_direct_value started to expand tokens:

What was the reason for this change I have no idea. We have reverted
back this change in our compiled luatex
because constantly playing with nodes reading we get issues with the
"write" node.
consistency with what write does when it writes data (also, returning a
token list as lua table and then expecting that to get expanded
explicitly otherwise is not that efficient)
we can consider adding getfield(w,"rawdata") for write and special
whatsits (maybe tl 2026); the current "data" access with expansion is
not a bug and it won't change

I think it is a bug. Luatex tries to expand data field content like
with \edef thats why you get \iffalse.
With older texlive (v0.76) the same example prints:
we now have luatex 1.12 so that is indeed old ... way too old to
bother about here
