Yes. The ISU uses a sort of international spelling, which is not necessarily the way the skater's name is spelled in their native alphabet. Cyrillic, in particular, gets mangled so much in ISU transliteration; for example, Plyushchenko becomes "Plushenko". I suppose that is because it is considered easier to remember for those who are not Cyrillic users. The letter which used to be transliterated as "shch" is sometimes written as "sch" in English now, as well.
A lot of names ending in "iy" get transliterated with just "i" or just "y". In the actual Cyrillic lettering, there really are two letters making the sound, i.e., "iy". Nowadays, some seem to feel that the "y" looks too much like the Cyrillic letter that stands for "u", so they hesitate to use the "y" in transliteration of the "iy" name ending. I hope I am not being too confusing. I am very tired from losing sleep, but I really did want to help explain the apparent changeability of names that were originally written in Cyrillic.
