The latest now is the point where a comment wants adding here, owing to
the fact that PUSH2 has no destination operands, while POP2 has no
source ones. Following the common pattern "mnem %<src>,%<dst>" DstVVVV is
indeed appropriate here, but the anomaly for PUSH2 imo wants clarifying.
Okay with such a comment added.

And then everything touched here also wants leaving alone in patch 1.
There's no reason to touch stuff twice when once suffices. Plus it
eliminates the need to add respective comment for POP2 there, which
you'd then replace by said PUSH2-related comment here.
