Jag tror att den officiella förklaringen är att detta inte var ett drag som delas av alla Vorta. Den första Vorta som de stöter på är ovanligt att ha den förmågan. En noggrannare (inklusive ur universums detaljer) beskrivning ges i minnet alpha:
Only one Vorta was demonstrated using telekinesis: Eris. As the DS9 writing staff put more thought into the Vorta following their initial appearance in "The Jem'Hadar", telekinesis was discarded and deemed a misstep that the writing team hoped viewers would forget. (Star Trek: Deep Space Nine Companion, p. 155) Ronald D. Moore stated, "Our internal rationale has been that Eris was given this ability for a specific purpose by the Founders (and maybe several other Vorta along with her) and that it is not a normal part of the Vorta 'recipe' in the Dominion." (AOL chat, 1998)
