yes, thats pretty standard motorcycle gearing. You need to remember, that although that fella is turning that by hand, at what? 50-60rpm? when its inside the gearbox and running it will be spinning much faster than that, so its a non-issue really. even if the dogs do meet in the way you describe, the gear will have rotated around enough to engage in under a second, so youll never notice. This is eliminated in cars with the advent of synchromesh (generally a small coneshape component that fits between the coupling sleeve and the relevant gear).
The lack of synchromesh (and the same issue you are asking about sort of) is also why you get that "clunk" when you engage first (because the gearbox is going from no engagement to engagement).
All that being said. in a motorcycle box like ours (or most modern motorcycle transmissions), it CAN still happen, making a bigger space between the dog teeth helps to reduce it though.
