    My jig is a kreg jig and only drills perpendicular holes. I suppose a jig could be made to attach the jig at 45 degrees.
    You could make a 45 degree block and using double sticky tape attach it to a flat surface. I will try that.

    How are the two images "opposite"?

    imagine where the screw tip goes. on the first photo its more towards the middle of the panel, from outside, to inside.

    on the 2nd photo, its the opposite, screwed from the inside of the box to the outside, so the screw tip is closer to the edge of the plywood base.

    Its thought that the first photo makes a stronger joint.

    I can see some potential for the second image method being "weaker" or cause some splitting. However, I have done them this way and not had any problem. With glue in the joint I suspect a true study of the methods would likely yield the same "strength" results. With the screws only there, it is a small enough difference in strength that if you were relying on that strength then you would be better off using a different method of reinforcing the joint.

    My view of it is either is fine and if you're looking for more strength then pick a different joint.

    I can't imagine there is any real rationale for that theory.

    Must be right because some guy made a YouTube video. That joint would have failed in a slightly different manner if the pockets had been on the other side. That's generally what happens when you screw a couple of blocks of cheese together.

    Mine too... and I don't pre-drill pocket hole screws. That really removes most of the reason I use them (which admittedly isn't often), which is convenience.
