Under certain conditions, the check rides on the larger/more complex aircraft could be counted for the smaller one(s) as well.
That is still possible. However probably more restricted than before. Airlines do that all the time, for example flying A320 and A330/350 with training credit. Which means that you have to have alternating simulator trainings, but both count for the other type as well. Mixed fleet flying has been heavily lobbied for by airbus of course, which might be the reason that it is still allowed. Althoug airbus did depart from that philosophy with the A350 which now has a common typerating with the A330, something boeing used to do. That allows a mixed fleet operation between three types now with A330, A350 and either A340 or A320. Still only one simulator event every six months, usually two days on the same type, one day LOFT and one day check.
