In the following document the second a is much nearer placed to the

Can one avoid this side effect of nested \math-command? When
building symbols it is not always easy to avoid such nestings.
it becomes a chicken-egg issue because one can argue that a wrapped
mathbin is no longer a pure bin and so ... it's again an indication that
a wrong boundingbox (width) relying on always some kind of italic to fix
it is a bad approach and recursively going into a bin (or whatever) node
to see if there is a nucleus chactacer would be yet another
'configureble option' ... all is possible but the more we get of that
the more one needs to be aware of it and provide control over the
opposite (keep in mind that such control is then a formula wide one as
math lists are only processed when fully collected)
