Standard size and full size refer to the image pixel height and width. If you upload an image larger than 2560 pixels on the longest edge it will upload at that original size. If you upload the same image through G+ it will be downsized automatically, but that's not the case with the Picasa API.
I can look into why the image file is smaller in bytes but would be interested to know if there is any visible difference in quality between the two. Otherwise your image was not downsized in the way that we typically refer. Let me know how those two look.
