If two generators run the same frequency at the same time with the same settings they will cancel each other out?

The two frequencies only cancel out if they are 180 degrees out of phase with each other which mimics what we see in the real world.

This is how things like the noise canceling headphones work; and in the case of Spooky2, only when Out 1 and Out 2 match frequency/amplitude, and Out 2 is 180 degrees out of phase from Out 1, does the output get canceled out.

Note for the technically minded: When we use a boost, Out 2's phase is flipped 180 degrees by the hardware. This why if you use Follow Out 1, the signals cancel out. Thus we have to flip the source signal 180 degrees by use of the Inverse + Sync option, so that it gets flipped twice, rendering Out 2's signal in phase with Out 1.
So, in the case of transmitting a frequency from multiple remotes, they shouldn't cancel out. I don't believe they re-enforce each other either due to the nature of the delivery. It is not much different than listening to a song from 2 speakers or 4 speakers. Just because you doubled the speakers does not mean the volume got twice as loud -- an oversimplified example to give context.

We don't stagger programs on remote as much as to prevent issue with them canceling out, but to allow time to pass so that the frequencies from multiple generators act as a repetitive value more frequently than a single generator could in the same time span. It is still generally accepted that number of repeats in a day directly correspond to efficacy rates via remote. Why repeat at all, because use of a static frequency via remote has shown to produce frequency poisoning effects in many.

Those who wish to explore running the same frequency on multiple remotes at the same time hopefully will provide valuable feedback that can help us flush this variable out.

Now in the case of using a remote and contact at the same time, and using the same frequency on both, there exists the possibility that the two will interact. Even if they do, the likelihood of them meeting 180 degrees out of phase is staggeringly low. What other effects may be had, only testing and time will tell.

In the case of running the same frequency from two contact sources, there does exists the condition that the two signals will meet in the body and interact. Again, the likelihood of them meeting 180 degrees out of phase is low. Meeting at various phase angles and attenuation states is high.

Most don't do this because of other issues, like the unpredictability that all current from both generators will return to to a single generator and fry gear. This is a totally different concern. So overall, from my point of view currently, you should not worry if you run the same frequency on multiple generators via remote. Staggering the programs so that there is time between transmission of that frequency is still a good idea, but not required. Having the same frequency from a remote and contact at the same time shouldn't cause great concern, and avoid running contact sessions from more than one generator at a time.
