Is my T-1 secretly a superhero?

It's my understanding that the numbers shown in the engines on the RTK screen indicate the satellite count for each signal being used in each engine's RTK computations. In other words, if a number appears in the grid for any given engine, that means both the Base and the Rover are listening to that signal within that constellation, and the Base is blasting that information to the Rover.

If that's the case (and correct me if I'm wrong there), then I'm pretty sure my Triumph-1 is a rogue vigilante! Looking at the options, I see that only GPS and GLO are enabled in the T-1 - Beidou and Galileo are both "0" for current/purchased/leased. However, my LS+ happily shows 4 constellations in use for RTK solutions. Interestingly, when connected to the T-1 base through the LS during base-rover setup, if I open the base GNSS status screen, for a few seconds I see satellites populated in all 4 constellations before they turn gray, as though they're suddenly "off limits" - almost like the T-1 realizes "oops, I'm not supposed to report these in use!".

Assuming both of my T-1's are doing the same sneaky stuff, that would absolutely explain the unexpectedly good performance I've gotten out of my trusty T-1 base-rover setup over the years, in canopy, etc... I've always assumed I was using 2 constellations!

Anyone else experience this sort of thing, or am I misinterpreting anything here?

Then after just a couple seconds (don't mind the satellite count itself, this is a test in the office window... the same "gray" results happen out in the open):

The small numbers in the colored boxes represent the signals being received from the base. GPS C/A for example is getting 7 signals from the rover and 6 signals from the base.

Beidou B1 is getting 7 signals at the rover and 1 signal at the base.

I could be wrong, but I think you're seeing what the Triumph-2 is able to see, more or less.
