Do you want me to confuse you more? Try this:

# if false then let _ = () in print_int 2; print_int 3;;

> # if false then print_int 2; print_int 3 else ();;
> Characters 39-43:

And this one:
# if false then let _ = () in print_int 2; print_int 3 else print_int 4;;

And this situation:
   if blahblah then
      thing1;
   thing2;
   thing3;
I decide to add a let..in for the thing1.

What you see:
   if blahblah then
      let x = e in
      thing1;
   thing2;
   thing3;
What you get:
   if blahblah then
      let x = e in
      thing1;
      thing2;
      thing3;
