You are correct. This will work, however, the math proves you are not getting the full force of straight in line wheels and mechanums have a tendency to be difficult to steer straight plus a tendency for the operator to over correct. That's why so many teams experiment with a gyro feedback to help drive straight and side to side. The low friction of the surface means that the gyro would try to stop a skid but only manage to spin the wheels really fast... the exact opposite of what you need. Slower speeds seem to give more control but they're... slower. speed will be a factor in this game almost as much as friction.
Just my 2 cents

Would the low amount of friction on the wheels allow
the robot to move like an omni-drive?
I don't know how slick the flooring is because I was not able to attend a Kick-off. 
But from what I have heard, it sounds pretty slippery.
Any guesses on how well this would work?
