Using the charge attack on the boltbrand,there is a slight chance to cause two explosions. However, whenever i use mines, there is never two explosions, rather it has two types. A close range and a far range explosion.
I was testing this with a guildie and his one has two explosions and he does not see two with mine either. This could be a graphics bug or it could be a bug cause my one has a UV against constructs low.

Sometimes, graphics means explosions don't always appear. if you have a far away explosion,the closer one was invisible.
This can happen with and of the brandish lines except for cautery sword. even with the 3* ones. I have 3, and all of them occasionally cause damagewhere my blade couldn't hit them, for seemingly no reason.
So don't worry-you have had 2 explosions
I have a blazebrand and its just the same, the chance of actually getting 2 explosions connect are really really low.
