I've definitely heard of Dom frenzy, but usually as an analog to sub frenzy - Dominants who are either new to the lifestyle or new to a subset of activities and suddenly want to go as far as they can as fast as they can, often disregarding safety and consent if it goes on too long.

I think what you're describing is likely a form of that frenzied state. Though depending on circumstances and personality, it might not be. Some folks tend to hyper fixate by nature. I'm one, and have to stay conscious of that in life in general as well as kink in particular. The same instinct that pushes me to listen to an album over and over til I have it memorized is also present when I try something new with a partner: I want to experience it again and again until I have total familiarity with it... and then I want to experience it more because it's so familiar.

Even if it doesn't cross safety lines, that's not always the best instinct to have with a partner. Just like my passenger might get frustrated when the CD loops around for a fourth time, it can be frustrating for a submissive to endure the same scene every session. So it's definitely something I'm mindful of, but I think hyper fixation only crosses the line into frenzy when paired with disregard for either consent or safety.
