$.mobile.changePage = function( toPage, options ) { }) missing releasePageTransitionLock() at the end

Hello guys, shouldn't there be also a  releasePageTransitionLock(); at the end of the function  $.mobile.changePage. 
according to what I have tested here:  http://stackoverflow.com/questions/12796742/mobile-changepage-not-working-with-phonegap-android-emulator there is missing or the variable isPageTransitioning could never get the false value.
