You're focusing on the first sentence; the reply was, I think, focusing on the second.

"The delta-V for such an orbit change is exceedingly small compared to the cost of a launch."

In that context, I think it seems appropriate to point out that it's not true as a categorical statement.

the "for such an orbit change" is the qualifying statement there, as opposed to "for any orbit change". It is clearly referring to the same category of orbit change being discussed in the preceding sentence.
