I favour the right hand on top of the stem method myself.
Me too. It's obviously safest. Like this:

I can't actually imagine that happening. Nowadays I don't have panniers anyhow, but when I did used to commute with panniers, they were never anywhere near heavy enough to have that sort of effect.
I doubt many modern racks would take the weight of panniers that would cause that.
Most modern racks are rated for 25kg loads. Plenty enough for the tail to wag to dog
Happens very easily, and it bit me several times when I was new to commuting. Just an ordinary hybrid bike, a standard Tortec rack and a single pannier containing a small laptop, a change of clothes and a pair of shoes. It made me adopt the one hand on the saddle, other on the bars method.
Yup, I've known it too. In your case sounds like the "mono-pannier" arrangement maybe contributed?
37kg minus 14kg for the bike, 3kg of water, 1-2kg for clothes, that leaves 18-20kg for the panniers if they're full, but most of the bike weight is supported on the wheel and my hand, so I can't see it needing much weight at all to overbalance it. The pannier CofG is ~0.5m from the axis of rotation, so they exert plenty of torque once they start to go.I can't actually imagine that happening.

My original pannier lasted for 36800 miles, 10500 of which were fully laden for touring.Most modern racks are rated for 25kg loads. Plenty enough for the tail to wag to dog
The bike isn't doing a wheelie, it's toppling, with panniers going to one side, and the front wheel coming out sideways from under the opposite side:I would have thought it would need a lot more than that to cause the bike to pivot backwards if the front wheel hit a bit of a bump. I was thinking of exactly that 25Kg limit on most modern racks when I made my comment.
The Centre of gravity of the panniers should be almost exactly above the rear axle, and it is only going to cause that type of pivoting if it is noticeably rearward of that, even with 25Kg in there.
Like this:the weight of the panniers causes the whole bike to rotate around an axis drawn from the point where I'm holding the stem to the point where the rear wheel contacts the road
