If you used an expression in CalculateField you could avoid needing to split and re-merge. Something likearcpy.CalculateField_management("in_memory/originalfc","ALPHA",'"A" if !attr! <= 0 else "B"',"PYTHON")

IN_MEMORY is a sort of simplified "geodatabase" but obviously in memory not on a disk. Now the important thing to appreciate is that it is like a geodatabase and thus honours the many specification, but not all, of a geodatabase.
I believe you have been unlucky enough to have chosen a geodatabase RESERVED field name, ALPHA. Suggest you call it something else like "myALPHA".
