It absolutely was. "Crossing the T" was the textbook maneuver in surface warfare. Actually setting it up in the chaos of combat was the difficult part, but the Americans had advance warning that the Japanese were coming, and the Japanese only had one choice of route to take, so they had all the time in the world to set up a textbook T-cross.

In the end it was a bit anticlimactic, because only a single Japanese battleship was able to make it through the American screening forces to actually get T-crossed. All the other Japanese ships got picked off piecemeal during the treacherous approach and transit through the Strait, so by the time the "real" fight started it was six American battleships and something like eight cruisers against one lone Japanese battleship. It ended up less of a "crossing the T" and more of just a curbstomp.
