I don't see why that would be confusing for regexp_replace
specifically, but I think N => count is a reasonable change to make.
However, I don't think this quite works:

+     then the <replaceable>count</replaceable>'th match of the pattern

An English speaker is more likely to understand what is meant by
"N'th" than what is meant by "count'th". Even if they can guess, it's
kinda strange-looking. I think it needs to be rephrased somehow, but
I'm not sure exactly how.
