"Is this the cause of some still writing assembler in uppercase?"
Can't speak for everyone else, but I've always done my assembler in upper case. IMHO it looks neater and is easier to follow the code - But maybe that's just habit.
Can't see anything wrong with doing it in upper case or lower case ... So long as the style is consistent.
Uppercase is fine for mnemonics, directives, etc, but lower (or mixed) case is definitely better for identifiers.
And comments should certainly not be written in ALL-CAPS.
