Question on S&H vs. T&H

Isn't the S&H switch actually more of a T&H on MG, MG8, MG16?

I think it is correctly characterized as a sample-and-hold function. When triggered, the module will generate either a random LFO or a sample-and-hold value. Presumably the source of the 'sample' is its own source of random noise.

With track-and-hold it is more like a gate is applied for a limited period and then you have the original sample pass through for another period. Almost like track-and-hold will use a gate: when it is high, the sample is held at a single voltage from the time of the onset of the gate and when it is low, the original sample passes through.

With the MG* modules, when it selects to return a sample-and-hold value, It just stays at that value. There is no time when the original sample passes through (the random noise).

I am basing my understanding of the differences from sample-and-hold and track-and-hold from this example: https://www.youtube.com/watch?v=KvjiKzBaTAs and this diagram: (a: S&H, b: T&H):
