This is late 1930's refined bazooka or late 1940s panzerfaust technology not Javelin or Bill.

You may want to look a bit more into this, in a nut shell you are right, however the angle of the cone and the stand off must be just right or it will not work well, maybe even less effective (depending on how off they are) than just basic HE. Getting the timing right so that when the round goes off by the time the jet is formed it is at the correct distance is complicated.
