(I assume you meant `M-:', not `M-e:'.)

Maybe someone can give a good reason why it doesn't work the first time.  If
not, please file a bug.

Note that this use of `M-tab' is a bit special: you are not invoking it, you are
asking about the binding.  That might have something to do with the problem
here.  I have never had Windows app switching get activated when I have invoked
`M-tab'.

Little in this world is guaranteed to work.
