It would certainly be correct that the first vote will take place on your amendment, but I think that it's also entirely proper, and probably a good thing, if the chair is willing to group together amendments that are in line conflict or that are very similar. Because most of these are very small variations, it would give the committee the very best opportunity to discuss and decide on precisely which variation it would prefer.
