Welcome to Russia! This is a normal setup, normally used for a '2 NDB Appoach'. Keep de needles aligned with eachother and you fly straight to the THR (like in Smolensk). Nowadays Russian airfields get VOR/DME more and more. They don't use it in any procedure except to crosscheck the distance on final. It's also helpful for old FMS systems which use DME updating only to calculate the position. Until roughly 2 years ago there weren't any, so no way you knew your distance to the field and whether or not you captured the correct G/S until coming overhead the OM (exept maybe FMS position which reverted to IRS-only at least 15 mins before due to missing navaids). Add to that the controllers instuction: "Descent to height 850m by QFE 939hPa" and you do the math.
