There is an indication of BB wanting to block the thing that messed him up considerably just moments ago.
I see no hint whatsoever for Law going for an attack except for trying to plant Kikoku inside Blackbeard.

The simplest answer is that both of them just went for an attack, Law had to stop his phasing and release his shockwave early because if he doesn’t then he’ll get hit by BB’s shockwaves first. He can’t continuously phase then simultaneously release an attack as shown with Puncture Wille. More like a one time release per sword length.
