Fred already mentioned about the option order.

Basically IM handles options in the order given, (except for a legacy
ordering which wyou should not rely on).

However I can not see why you should have a loss of quality with the
above.  Append does not re-sample the image or generate new colors.
Also the PNG format may cause a small file size change rather than a
quality effect.  so that could not be it.

Can you post the URL's of two small images whcih when appended causes
the loss of quality.
