Shikadai changes his sign which changes his attack from a single stretched shadow into a giant circular one and catches every Shaowclone (and Boruto) at once.

Before that, Shikadai keeps Boruto busy with his shadowbind, so there wasn't much for Boruto to try. The fact that Boruto sent a clone against Shikadai implies he intended to let it get caught (and the 4-direction attack was the real one). The fact that Boruto gets caught by this implies he didn't know about Shikadai's circular shadow.

Other tactics (Boruto stream for instance) would imply he knew more than he actually did.
