[NAFEX] Planting replacement trees in same site as failed trees

With apples there is something called 'replant disease' and it is not usually recommended to plant a new apple tree in the same place where there was a tree which failed to survive.

My guess is that that has to do with trees that fail due to conditions.  If
soil disease, soil pH, or something else site-specific killed a tree, an
identical tree might have the same problem.

Can anyone comment on a bit of conventional wisdom I have run across?
"Do not replace a failed tree with the same type of tree at a single
site."

My planting sites are limited. I have replaced nut trees (pecan, Chinese
chestnut) that have had apparent graft failures with subsequent pecans
and Chinese chestnut.  I plan to do so with my failed espalier apples.

I have dug deeper into reference books to see a scientific reason (other
than disease) why I should not reuse a site.  I cannot find an
explanation.

Am I courting failure replanting at a site?
