In that case the first six years of iPhone models were also minis. None were cancelled due to low sales. The original SE was also not cancelled due to low sales, it continued to sell extremely well for years after its release. Apart from the 12/13 minis, the only model that had low sales was the 5C, which is actually a little larger than the 5S.
The rule for the SE is that it always has the design of second most recent hardware design, regardless of size.
If Apple re-introduces a mini, that will be the first such 'cycle.'
Dimensions:
SE1: 123.8 x 58.6 x 7.6
Mini 13: 131.5 x 64.2 x 7.65
Counting the original SE as a mini is perfectly reasonable.
It's also quite clearly what the grandparent comment was referring to.
