No. Modifications to a Power carry over to its Repeat. (p. 19)
Remember that if there are explicit instructions about where to Repeat a Power, those take priority. So if a Power Card says "Repeat this Power in an adjacent land", you may (and must) target a land adjacent to the original, rather than choosing a new target the usual way.
