I had three tricots among my Pereskia seedlings in 2009. Two (that were perfectly symmetrical) turned into normal looking plants when growing true leaves. One (that had 1 cotyledon smaller than the others) however turned into a dwarf version with stronger ramification. The whole plantlet only had the size of 1 leave of his sipplings, yet looked like a micro tree. Unfortunately it died when someone accidently broke its tiny stem...).
In semps it might lead to more true leaves or double (triple?) rosettes. I don't think it leads to cresting. But maybe it will also turn into a normal plant once it starts its first true leaves. Will keep this one under special observation!
Enclosed fotos of that Pereskia seedling and a leave of his (partly variegated) sister. In the second foto you can still see the three cotyledons:
