I don't know if the article writer is north American, or possibly not familiar with traditional/native English, else they would know they are completely wrong it not being English.
The author didn't say it was not English.
The author wrote: "I can't use "else" as a conjunction in normal speech, only in computer programs."
No doubt people use 'else' as a conjunction now, due to the influence of programming.
To show the author is completely wrong requires finding pre-1959 uses of 'else' in a conjunction.
