Based on the following game, the plan to blow the Modern out of the water with Be3, Qd2, h4 isn't the only successful idea in the position. In fact after 4. ... a6 such a direct strategy can backfire on White, which is probably why Weber chose the f4-f5 idea instead. Having broken up the king side pawns his pieces then went straight for the King, and Rudd resigned just as he was about to drop the rook on a8.
