That is a misstatement. \partCombine does not use tags in any manner.
It plays the music it is given and records the results. Then it
combines the played results. I am surprised that \keepWithTag should
actually be doing anything here.

That won't work. You need to use
\partCombine \keepWithTag versionI \instA \instB
instead.
