No it has nothing to do with the records or their tempo at all. There are four lines of dots on the platter, one for -3, one for 0, one for +3 and one for +6. When the pitch is at -3, the first line will look like it's stationary, then at 0 the second will look stationary and so on. If you wanted to check the accuracy of your pitch control you would do so by using the dots.

If when the platter is touched, one of the lines looks sationary for a moment, it obviously just means that the platter is temporarily running at -3 (or whichever it is), nothing else.

Unfortunately this isn't much of a trick and the fact that it may result in a good mix is purely coincidental. Best keep away from the platter where possible anyway, and compensate as much as possible with the pitch itself. I'd touch the platter myself a bit, but as little as possible.
