[Coco] is this a bug?

Further observations:

I tried a bunch of other instruction in the Motorola mode of the 
assembler and they all assemble correctly with extended addressing as 
expected.  Interestingly, if I use the SETDP directive to tell the 
assembler that I want it to use direct addressing in page $20 it still 
errors out.  Apparently this time the assembler regarded it as extended 
addressing in the first pass and then direct in the second pass:
