'Give Way' has the same meaning as it does on the roads. At a junction the 'Give Way' sign indicates that the traffic on the road you are entering has priority. This however does not stop you entering that road, quite often ahead of traffic already on it, as long as it is safe to do so. Therefore in aviation terms by issuing a 'give way' instruction you are indicating that a certain aircraft has priority but you can continue ahead of it if safe to do so. If it had the same meaning as 'after the', then for a start we would not have two different instructions, and secondly MATS PT1 would not prohibit the use of the 'give way' instruction to resolve conflictions between vehicles and aircraft.
