Does this sign warn you of approaching an intersection with a one-way street without right of way from which traffic flows from the left side?

The sign visible in the recording is A-6b "intersection with a minor road on the left side". This sign warns of approaching an intersection with a subordinate road, but its definition does not contain information about whether this road is one-way. According to § 5 of the regulation on road signs and signals, this sign only indicates the existence of a side road on the left without specifying its traffic organisation (one-way or two-way).
