(Windows batch) Goto within if block behaves very strangely

If I take the following Windows batch code snippet and run it:

echo foo
if 1 == 1 (
    echo bar
    goto asdf
    :asdf
    echo baz
) else (
    echo quux
)

The output I would expect is:

foo
bar
baz

But instead I get:

foo
bar
baz
quux

If I comment out the goto asdf line, it gives the output I expect. The echo quux line should never be exectuted, so why is the existence of the goto causing that to happen?

UPDATE: For what it's worth, here's a workaround that correctly does what I originally intended:

goto BEGIN

:doit
    echo bar
    goto asdf
    :asdf
    echo baz
    goto :EOF

:BEGIN

echo foo
if 1 == 1 (
    call :doit
) else (
    echo quux
)

However, this doesn't answer my original question.
