It is about the heat of solution, and the fact that when sulfuric acid is in the majority, the water will heat up past boiling quickly, resulting in rapid evolution of steamy acid droplets, or even an explosion of steam. Acid into water results in a majority of water to carry the heat, and in that case, there is enough water to carry all the heat without boiling.

James Stewart gave the exact same answer that I would have given, which is based on the heat of this exothermic reaction. Also, as stated by another person, this same concern also exist when mixing a strong base with water.
