I haven't tried your code which seems render the same output like what we do:
Begin Trans
lupdateok = .T.
If !TableUpdate(1,.t.,'view_a')
    lupdateok = .F.
Endif
If lupdateok And !TableUpdate(1,.t.,'view_b')
    lupdateok = .F.
Endif

If lupdateOk
    End Trans   
else
    Rollback
Endif
We usually put this on the save method of the form.
