They're not wrong really. It is gibberish on it's own. We don't know where in memory that it starts or the places it is referencing in the jumps. If it were ASM source code those jumps would likely contain labels instead of just raw dogging memory locations.
The fact that it just so happens to be from COMMAND.COM from MS-DOS 3 is a wonderful bit of detective work, but it doesn't make the snippet any less gibberish.
For example, taken out of its original context, this sentence fragment from your comment is meaningless:
"that definition, any language"
The code is not gibberish, but the way it was put there, missing information, etc, makes it so
This is a huge problem with SO, the person making the question is not usually the most qualified to decide and they usually won't come back to check for further answers.
One of many reasons I stopped answering a long time ago.
IIRC they recently changed the default sorting of answers to not always put the accepted one first to try to help with that common misconception.
