EYMS 121/744/X21 to domestic driver hours rules?

Based on registrations showing on the VOSA website today, plus this from earlier in the week, it seems that from June the 121/X21 (Hull-Scarborough) and 744 (Bridlington-York) will be worked under domestic rather than EU driver hours rules.

It seems the 121 will be 'split' at Driffield and Bridlington, the 744 'split' at Pocklington and the Summer only X21 'split' at Beverley and Bridlington.
