As far as I can tell, both modes give the same total number of points at max level for a new character (100 for the player and 80 for the squad mates).
It was broken in the original release, so that might be causing some weirdness if you're using an existing save.
I did a test run for the heck of it. I don't have the image from one of the chracter creations, but I finished that one using classic mode starting at lvl 57 (lvl 29 on legendary). After getting to 60, I earned 3 talent point for each of the final three levels. On another creation that I used as an imprt to ME2, it was also on lvl 29/57. There I ran the game out on legendary and got 2 points, one less than running at classic from lvls 58-60. As you can see, when I hit lvl 30, I got just 2 points.
Is this a new or existing (pre-patch) save? And was it already Level 29 before the patch?
No, even then, a pre-patch save wouldn't make the patch not work. Before the patch, I couldn't advance to 30 on legendary,.
The only issue I can confirm is that if you are Level 59 on classic mode and switch to legendary (will show up as Level 29), you still can't level up to 30 (you have to switch back to classic for the final level).
Every combination I looked at always gives the same number of talent points when reaching max level, but I only have access to characters created after the patch. It's possible that the fix is not retroactive in all cases or there's something specific with your playthrough or with the game on Xbox.
