I don't think low temp altimetry would be a factor in this. They where on a glideslope. The glideslope is not affected by temp errors. If they had gone lower than DH due to uncorrected cold altimeter they would have scraped the runway, not the loc antenna.
This looks more like a "decision, going visual", followed by a lowering of the nose trying to see better followed by someone realizing that they should throw it away.
They were extremely lucky and got off by the skin of their teeth. They certainly won't be able to blame this on the old favorite, "Russian equipment".
