Is this correct English? Those are two simple sentences. Shouldn't it either be split into two sentences, joined by a conjunction such as "and", or have a semicolon joining them instead of a comma?
You are right. A comma is not the correct punctuation here. It should be a full stop or, like you said, a semicolon.
3 times in a row the same sentence. Ist that intentional?
Perhaps it's waiting for you to deliver the punchline? :P
