Upload Document with default save button does't work

I'm not entirely surprised that this does not work, actually. The way Appian handles document uploads is through temporary document IDs. When you initially upload the document on the form, the document is put into a temporary folder and given a temporary document id. When a submit widget button is called, it updates all PVs of type document with new document IDs, as well as moves the documents to the appropriate folders.

Since the save button defaultly in Appian does not actually submit the form, it is not really plausible to have uploaded documents be saved as well, since Appian would then re-do the logic for changing the document ID when you do actually submit the form.

The way we have handled this in the past is to, as you have done, have a custom save button of type submit, and to have a separate PV for previously uploaded documents and for newly uploaded documents. You would also need to add SAIL and some other logic to handle users deleting previously uploaded files though.

It's a bit of a frustrating limitation of the default save, but I can see why the limitation is there.
