No... it's less clear too. The verb is never isolated from the rest of the sentence by a comma, but a list of nouns will be isolated by commas, even if the conjunction is missing for brevity in a title. Separating "returns" like that makes it appear even more to be a noun, which is the thing that the original comment was confused by. Correct interpretation of the title relies on the reader realizing that it is a verb in this context, and the comma does not help with that.

Given the ongoing mess with the AMD 7900 XTX GPU vapor chambers, I initially interpreted the title to mean there was some problem with AMD laptops, so System76 was offering returns only for those laptops with AMD chips. That is not the case.
