First, multibutton is broken. Proof:
Turing:

buttonchoose ("multibutton")
setscreen ("offscreenonly")
var button : int
loop
    cls
    mousewhere (button, button, button)
    put button
    View.Update
end loop

It always only shows either 1, 10, or 100. According to the documentation, it should show values such as 101 when you left and right click simultaneously.

The tutorial part:
I realized that you could take the button value mod 8, and bit 0 of the result would be if you left clicked, bit 1 would be if you middle clicked, and bit 2 would be if you right clicked. But since it's broken, this tip is temporarily useless until it gets fixed.

When life gives you lemons, grow your own oranges to make orange juice!
Turing:
Mouse.ButtonChoose ("multibutton")
View.Set ("offscreenonly")

const Buttons : array 1 .. 3 of string := init ("Left", "Middle", "Right")
var x, y, btnNumber, DummyVar : int
var ButtonPressed : array 1 .. 3 of boolean := init (false, false, false)

loop
    if Mouse.ButtonMoved ("down") then
        Mouse.ButtonWait ("down", DummyVar, DummyVar, btnNumber, DummyVar)
        ButtonPressed (btnNumber) := true
    end if

    if Mouse.ButtonMoved ("up") then
        Mouse.ButtonWait ("up", DummyVar, DummyVar, btnNumber, DummyVar)
        ButtonPressed (btnNumber) := false
    end if

    Mouse.Where (x, y, DummyVar)
    cls
    put "Mouse is at x: ", x, " and y: ", y
    for but : 1 .. 3
        if ButtonPressed (but) then
            put "The ", Buttons (but), " button is pressed."
        end if
    end for
    View.Update
end loop

Hope this helps you!

It doesn't work when the mouse is outside of the window though.

That's true, when the turing window is not active it does not receive mouse events. Most of the time, this shouldn't be too much of a problem since you don't click outside the Turing window to do stuff in the Turing window.

Here's an update to my previous code using Mouse.Where to the best of its ability (like you showed it's not functioning properly):
Turing:
Mouse.ButtonChoose ("multibutton")
View.Set ("offscreenonly")

const Buttons : array 1 .. 3 of string := init ("Left", "Middle", "Right")
var x, y, btnNumber, DummyVar, ButtonCheck, ButtonLast : int := 0
var ButtonPressed : array 1 .. 3 of boolean := init (false, false, false)

loop
    if Mouse.ButtonMoved ("down") then
        Mouse.ButtonWait ("down", DummyVar, DummyVar, btnNumber, DummyVar)
        ButtonPressed (btnNumber) := true
    end if

    if Mouse.ButtonMoved ("up") then
        Mouse.ButtonWait ("up", DummyVar, DummyVar, btnNumber, DummyVar)
        ButtonPressed (btnNumber) := false
    end if

    Mouse.Where (x, y, ButtonCheck)
    cls
    put "Mouse is at x: ", x, " and y: ", y

    if ButtonCheck ~= ButtonLast then % Extra check for when the mouse is outside the window.
        for but : 1 .. 3
            if ButtonCheck = 0 or ButtonCheck > 10 ** (but - 1) then
                ButtonPressed (but) := false
            elsif ButtonCheck = 10 ** (but - 1) then
                ButtonPressed (but) := true
            end if
        end for
        ButtonLast := ButtonCheck
    end if

    for but : 1 .. 3
        if ButtonPressed (but) then
            put "The ", Buttons (but), " button is pressed."
        end if
    end for
    View.Update
end loop

Overall, it seems we can't get full information about mouse buttons when the mouse is not in an active Turing window. On the other hand, this should rarely be troublesome as you don't tend to care about mouse input when the mouse is not in the window.
