I went back and checked, it was actually that someone recommended a bit different combination, something like 633,963... that gives tremolo, comparison of 600,900 and below it 633,963
I'll bet it was 639, 963! Because those are Solfeggio frequencies. (They just permute the digits.)
That would indeed give you tremolo, since they are close to harmonic but not quite.
If only it were 642,963, then they would be perfect harmonics of 321, no tremolo.
But instead of 642, we have 639... a beat frequency of 3 Hz!! Just as you reported.
(That is a sort of "ghost" beat frequency, since the 642 isn't really there, but the 963 beats against it in a similar way because it shares enough structure.)
This a great technique for putting vibrations into those funscript conversions, and I have played with it a lot. Success is hit-or-miss, especially if you don't generate the frequencies in separate runs to control relative volume. Also, I find that combos that feel good for some funscripts don't feel good for others. It depends a lot on stroke speed and range.

But as you said, safest option is to generate each of frequencies separately and then manually mix them with different volumes.
Dynamically adjusting that during the session would be very powerful, like what diglet is doing.
