I just read fight between Issei and Euclid and about the dragons that divide and reflect but it didn't say anything about Dividing Gear being nolonger accessible but more rather he won't need to because of the little dragons.

Plus I can only assume that he got this new ability because of the Dividing Gear relation between Albion and Ddraig. Right now I can only wait until it's made official in the novel.
