So why look in the cockpit and crosscheck instruments, when the information of the NAV, the baro altitude of the PF and the information from ATC draws a picture of "everything is ok".
... because they should be well aware that this kind of approach procedure only makes sense when they report back their altitude? I just cannot imagine them not knowing that in an RSL approach they can expect a margin error of 100 m with respect to altitude. And they knew how old and imprecise the aerodrome equipment was.

the speed was fast, it dropped way below glidepath and then below decision altitude and acording to ATC everything looks normal until 45 meters above ground.

That does not fit.
What about the expected trajectory? This is a page from the manual of Tu-154M:

For the vertical speed of 8 m/s, couldn't ATC have expected them to go a bit lower still before the go-around?
