It tells a deeper story - that senior Russian Officers feel they have to be at the front...
There are good reasons for seniors to be at/near the front: seeing the reality of the situation rather than a filtered version, and providing leadership when your soldiers are going through difficult times.
But it can also be a sign that the communications are ratshit and you need to be telling CO/OC's to their faces what you want them to do, or worse, that without the senior standing over them and whipping them on, they'll find reasons not to do it...
Communications, perhaps, but this speaks to unit morale pretty strongly, in my view.
Long story short: behaviouralists like to do rats-in-mazes experiments, and although you can't apply this wholesale to people, there are definitely results that emerge which do translate across to human behaviour. One of those is that if you do your "operant conditioning" (training to do what you should do) on the basis of negative reinforcement, it works...but it doesn't "stick". You need to have the dude-in-charge cracking the whip on a regular basis to maintain motivation. If, OTOH, you do your conditioning on a positive reinforcement basis, ie. by all the stuff they now teach in officer school, where you're teaching firm, strong, direct,
positive leadership and which the old hands do a kind of "harrumph, we didn't have this nonsense in my day" thing about, you find that you don't actually have to loom over them constantly, so long as they're motivated to do what they need to do, and there are regular bits of positive (and critical, where necessary) reinforcement going on in between times. And it's no surprise that, in commando or other special forces units, that's exactly what happens. You're not going to have some sergeant screaming at you that your stable belt isn't properly blancoed, because it is assumed that your self-motivation is good enough that you don't have to be yelled at about it. Etc.
It's reasonably obvious from the general narrative about how the Russian soldiers are operating, that there isn't any real sense of a positive desire to do what they're supposed to do, so much as a more slacking off culture where they're only running about and standing to attention when there's someone shouting at them.
Obviously, in those circumstances, some of those more prestige units realised that they were going to need their O/C on the ground doing the motivating, and...sniper.
