The call was correct throw. It was not high amplitude because Zaseev's legs swung to the side instead of arching over the top (if it had it would have been 4, at least by last years rules). This was absolutely the correct call because he did not land in danger.
The reason it is confusing is because we've all seen this type of throw incorrectly called 4 in the past.
Here is the match:
I originally argued your same point. Another poster said they changed the rules. Here are the current rules.

from page 29
– Grand Amplitude Throw Any action or hold by a wrestler in the standing position that causes his opponent to lose all contact with the ground, controls him, makes him describe a broadly sweeping curve in the air, and brings him to the ground in a direct and immediate danger position shall be considered a “Grand Amplitude” throw.
In the "parterre" position, any complete lift from the ground executed by the attacking wrestler, whether the attacked wrestler lands in neutral position (4 points) or in a danger position (5 points), is also considered a grand amplitude throw.
from page 30
- To the wrestler performing a hold in a standing position, which brings his opponent into a danger position in a continuous et fluid manner.
- For any hold executed by raising a wrestler from the ground and bringing his opponent into a danger position, over a short amplitude, even if one or both of the attacking wrestler’s knees are on the ground.
- To the wrestler who executes a grand amplitude hold which does not place the opponent in a direct and immediate danger position.
