I think root cause is SIGTERM (just guessing) ...

Certainly ... I recommend "at" command. It capture STDOUT/STDERROR and
send it to mail. But why wait :-)
By the way, test following to understand real reason why you had trouble ...
Your console is used by shutdown and upon killing ssh connection,
shutdown program get signal since its connected terminal dies.
Test1:
redirect STDOUT/STDERR
$ sudo shutdown -h +1 >/dev/null 2>/dev/null &
Test 2:
run shutdown in screen program.
