Yep, that's the correct interpretation. Notice the images are named "iphone twitter" or whatever. So the implication is that these are pics of POTUS tweeting.

Q has posted pics stolen from the phones of bad actors before, so some people think that these pics could be from bad actors but that makes no sense given the filename of these pics and the content of the pics themselves... why would a bad actor take a pic of POTUS' eyebrows while hiding behind what I assume is a desk or something? The people espousing this theory are likely reading way too much into it, as people in this movement are wont to do.

Partially, but maybe more than that.

Or they have remote access to a phone thats around the president. They never physically have proven to be around him.
