Interesting.  That explains the difference:  The \rho made the radical
big enough to switch to the extensible, unslanted version.

My math-typography sense is far from developed, and mostly comes from
having read lots of math books.  With that caveat, my gut feelings are
that (1) the switch from slant to upright is a bit surprising for a
reader, and (2) that the slant version is more common, so an
always-upright radical would also be a bit surprising.

But perhaps you or others with a more developed typographical eye have a
more principled way of judging?
