Please try to customize 'next-error-find-buffer-function' to this value:
(const :tag "Current buffer if next-error capable and outside navigation"
next-error-buffer-unnavigated-current)
It provides the behavior that you described.

The doc for `next-error' says:
<quote>
C-x ` normally uses the most recently started
compilation, grep, or occur buffer. It can also operate on any
buffer with output from the M-x compile, M-x grep commands, or,
more generally, on any buffer in Compilation mode or with
Compilation Minor mode enabled, or any buffer in which
‘next-error-function’ is bound to an appropriate function.
To specify use of a particular buffer for error messages, type
C-x ` in that buffer. You can also use the command
‘next-error-select-buffer’ to select the buffer to use for the subsequent
invocation of ‘next-error’.
</quote>
I interpreted that to mean that if I create e.g. two `grep' buffers and
rename them uniquely to `*grep*<2>' and `*grep<3>', then switching
to one or the other of them and calling `next-error' would use the hits
from that buffer. However it always uses the hits from the last-used grep
buffer and I have to change that explicitly, by calling
`next-error-select-buffer', instead of letting the current buffer
determine it.
The problem is caused by `next-error-find-buffer' which does things in
the (IMO) wrong order: it first checks for next-error-last-buffer and
then it checks for the current buffer.
Here is a patch to reverse the order:
