As a Hebrew speaker, I have to say that even though one should stick to English in code, paamayim nekudotayim was probably used because it rhymes; it has rhythm; it sounds like nothing you would say in ordinary circumstances.
There are a lot of words in French or Japanese that rhyme with keywords or English variable names in the projects I am working on. But I don't think my PO would be very happy if someone called him at 3 'o clock asking what the hell that line in the logs means.
