 #### Delayed transitions
 
-Transitions can execute immediately or after a certain time has elapsed. If a transition has no time delay it will be executed immediately (within the same frame). If a transition has a time delay, it will be executed after the time delay has elapsed but only if the state to which the transition belongs is still active and was not left temporarily. Once a state is left, all transitions which were queued for execution will be discarded. There is one exception to this rule, when you are using history states. When you leave a state and re-enter it through a history state, then any pending transition will be resumed as if you had never left the state.
+Transitions can execute immediately or after a certain time has elapsed. If a transition has no time delay it will be executed immediately (within the same frame). If a transition has a time delay, it will be marked as pending and executed after the time delay has elapsed but only if the state to which the transition belongs is still active at this time and was not left temporarily. Only one transition can ever be active or pending for any given state. So if another transition is executed for a state while one is pending, the pending transition will be discarded. A pending transition is also cancelled when the state is left through other means (e.g. because a parent state got deactivated). There is one exception to this rule, when you are using history states. When you leave a state and re-enter it through a history state, then any pending transition will be resumed as if you had never left the state.
