Yes this was mentioned multiple times already and it's not only skill checks that get effected, party comments are lost this way as wel and it can lead to strange combat start.
Dialogue cutsceens could do with better party implementation and that goes double for skill checks in those.
Not sure why they do it this way, maybe it's multiplayer? Unlikely that it would be inexpraince in dialogue cutsceens.
At start of EA it was even more strage (same as in DoS 2 if i remember right) where you could have the same conversation mutiple times and get multiple items, do checks multiple times so if you failed a check you could redo it for free 3 more itmes with different companions.
As far as i know this was fixed. This party checks/comments would be the next step in improvement.
Bioware and other devs don't have such problems as far as i know and it leads to better party atmosphere where you have the whole team participating. Even if it's just a tiny comment still worth it, especially if companions can save the day with a good check pass and outcome cutsceen that comes wiht it.
