Luis Sequeira alraedy pointed out the source of the error, namely, the spurious “[1]” in the definitions of \distX and \disY.

Here I wanted to point out that you may need to adjust the spacing, since (X, \distX) gives, to my eye, too much space before the closing parenthesis. By contrast, something like...

	\newcommand{\distone}{\ensuremath{\distsub{1}}}

…used, say, in "$(X,\distone)$”, looks OK to me.
