Your phone's browser is bad and/or outdated, and therefore can't get URLs directly from images.
For the record clicking "Open image in new tab" and copying from the address bar at the top should also have given you the image URL. There's always a way, don't be afraid of clicking buttons to find it.
The second image is from JMccovery post right? They added a built in link to it's thread, so I'm guessing that's what you would actually get if you did "Copy link address" on it. The first section of options is reacting to that link, the second group is the actual image options, which are the same for both signatures, there's nothing specific about the LiL image.
If you don't believe me, try your own Ripples signature (doesn't have a built in link), it'll act just like the LiL sig in the first image, or try your own new LiL signature (does have a built in link) and it'll act like the Ripples sig in the second image.
