No, if the charger is rated for 6-volt batteries up to 110 amp-hour capacity, Noco is saying that it is not adequate for a battery (such as the optional 6-volt Interstates from Escape) with a capacity of 225 amp-hours. Of course, it may work acceptably anyway...
Combining two batteries in series adds their voltages, and not their capacities. For the combination of two 6-volt batteries to be one 225 amp-hour and 12 volt battery bank, each of the 6-volt batteries must have a capacity of 225 amp-hours (which is what Escape offers).
