This statement does mean that the maximum rated main breaker can only be 125 amp?
The way I read that is 'for load centers with 125 amp mains, whatever the double+ is indicating is limited to 100 amp max'. But I can't read the label clearly enough to see what the double+ is referring to.
Would that apply to the mains? No.
Some where on the label, out of view, it should state 'XXX amp main rating', which would indicate the rating of the mains (in this case, the bus bars).
My guess is that the double+ is after something which refers to the branch breaker tab maximum size, and 100 amp is not uncommon for that rating, although some are 125 amp, 150 amp, not sure if I've seen a 200 amp rated branch breaker tab - but there could be some.
The other answers were quicker, so I ignored those items.
