After fixing the attached file to remove the carriage returns, I was able
to reproduce the fault using Bash v5.2.0 rc2

Running with « bash-5.2.0-r2 -x ConsecutiveHereDocStringBug », it appears
that the "cat" on the line following the assignment to uS is subsumed into
it, and then the redirection on the assignment is ignored.

(I discovered this when I attempted to insert « printf HERE\\n >&2 »
between the assignment and the cat, only to then see HERE\n: command not
found.)

Indeed, it appears that the command following the "do" always absorbs the
first word from the second command, despite the line break between them.

This does seem like a fairly serious issue if it's present in the 5.2.0
release.
