The pass through works for me too. You just have to be precise. The site looks very promising. In the 4.Ng5 Two Knights, the main line (i.e., the top choice in the analysis tree) appears to follow the game Morozevich-Graf, Alushta 1994.
Note that after 18.Qe1, the move 18..Rfe8 may be an improvement over Graf's 18..c5.
After 18..c5, a later game showed that White could play 19.Nxe4 and trade down to a favorable ending.
Also, after the game continuation 18..c5 19.Kh1, the improvement Bb7! was better than Graf's 19..Nc6, at least according to Morozevich and Blatny.
If you have any further ideas about 18...Rfe8, this would be an excellent occasion for your submitting a brief (or not so brief) analysis. I would be happy to make you a charter (permanent) member of the working group, if you would message me privately.
However, if you look here:
https://1e5.chesstheory.org/p.php?z=pt&a=39801&b=0&c=39801&d=0you will see that 18...Rfe8 has been played in four games, and the various continuations. It's possible that you may have to register (a free procedure) to see this, because mere guests are not allowed to see the tree to its full extent.
The line that you mention (18...c5) is indeed found on the most frequently played (top) path, but it is not part of the public repertoire (visible if you use Settings and set "highlight something" to "public repertoire for Black), which uses 10...Bc5.
