Alternate merge is a narrow tool on purpose
Interleave odd and even scan documents.
Interleaving only works when the scan order is understood
This job is useful for duplex documents scanned as separate odd-page and even-page stacks. The direction of the second stack matters; a reversed scan can produce a perfectly merged file in the wrong reading order.
The starting order matters. If one scan set is reversed, fix that before you interleave the files.
Where Alternate merge fits cleanly
Combine odd and even duplex scan batches. Merge front-side and back-side scans. Both jobs fit because they ask the tool to do exactly what its output is designed for, without adding an unrelated conversion.
The point where Alternate merge stops helping
Use ordinary Merge PDF when you simply want one document after another. Alternate merge is for interleaving two page sequences, not concatenating them.
