Will the plain text way still work?
\ifodd\pageno foo \else bar \fi
This works only correct when used used in the page header or footer texts which
are added after the page is finished and then you can use context’s
\doifoddpageelse command. When used in the running text the test can fail when
you have a text which ends at the top of the page which was processed by tex
when it was on the previous page and the output was moved to the next page
because there wasn’t enough space.

Thanks Hans! Works nicely (as always).
Just as minor comment in case someone faces the same problem:
There's already a

So to make this fix work I had to redefine / replace the original command
instead of just putting it there.
