You can. But the stream after merging and before mixing will have two
front-left channels and two front-right channels, this is not a valid
channel layout. af_amerge will therefore pick any channel layout with four
channels and stick it on the stream, just because a channel layout is
mandatory.

Please read the documentation of amerge, it explains that. If you find it
unclear, questions about its wording or suggestions to make it clearer are
welcome.
