No, it will point to pico.  But I see one point here, which I will address:

What you're alluding to here is a notion of a primary "default" candidate,
which is currently not in pkg_alternatives.  Currently it just puts the
candidates in arbitrary order.  (Order of installation, or simply sorted by
pathname on a "rebuild".)

It should be possible to add more logic to pkg_alternatives to provide such
a "default" for this situation, which would take effect automatically -- if
the wrapper in question is still in "auto" mode.

So if nano is installed first, bin/pico points to it.  Then, as long as
bin/pico is left in "auto" mode, installing editors/pico later will re-point
the alternative to uwpico.

Would this help?

I've contacted you offlist about this; it's not related to njabl.
