Yet another parking sign question

[jperickson]

I've always found it a bit awkward that most street-side parking signs approach it from a "negative" prospective. In other words, the sign meaning "you can park here most of the time" is really a "no parking" sign. But then at times there is also the blue P sign which is a "positive" sign, meaning it's a "you can park here" sign directly.

Anyways, I try to move on with my life... Until yesterday when I realized I was at an intersection where both systems seemed to be in use. The two signs below are from two streets that meet at a 90-degree angle. They seem to say the exact same info (except the specific day of week), but use different systems... Does anyone know if there is a meaningful difference or why this would happen? By eye, the streets otherwise look like they should be treated identically by zoning. I realize the very top sign is "no parking" and the other is "no parking, no standing", but I still don't see how that should affect the second half of the sign.

And also: are you ever allowed to park overnight with either sign without the 2/B permit?

Any enlightenment is appreciated. Thank you!
