Shape of logs of insect screen frame

frame

I am about to create a frame for a mosquito net, and I have read in various places that the end of the logs of the frame should be cut diagonally, and the logs joined along this diagonal cut (see fig. 1), instead of just joining them along the edges (fig.2)
I never found an explanation, why is the diagonal cut better. So my question is: what is the advantage of this diagonal cut? Is it just aesthetic or is it also more stable in some way?

The 45 deg cut gives more surface area for glue if you glue and more strength , 90,s are easy and can be nailed or glued but any paralyx (not totally square) will show more and be weaker than a 45. I have done both in the past but 45's look professional and last longer. Just look at your door frames, sliding screen doors and you will find 45's not 90's
