Yamada Sensei can be seen here breaking Uke‘s grip and then regrabbing to continue the nikyo formation.

A key point is to stop the strike momentarily, then to grab Uke‘s wrist and continue the kotegaeshi technique. Doshu does not grab Uke‘s hand as he thrusts. This is the kihon, shinsa version.1

Tissier Sensei:

Shomenuchi iriminage ura variation

In this instance, he entered directly into and against Uke and was able to come behind him easily and smoothly to continue the iriminage. This is from the following video at [2:09].

I found a clip of Steven Seagal executing an exciting variation of yokomenuchi kotegaeshi where he parries the yokomenuchi with his forearm and glides around it. This would be an analog of shomenuchi kotegaeshi with an initial sokumen-irimi. See around [0:55] for the technique in question1.

Translated as “left and right exercise”, sayu undo is shown here in a Hombu dojo aikitaiso clip.

At the end of the clip there is also haishin undo (背伸運動) which is what we usually do at the end of each practice.

Nishio Sensei demonstrates katatedori kaiten-osae with a bokuto in this VHS video1

From my understanding, it looks as if Sensei keeps Uke‘s arm high as in nikyo ura, then turns about its axis. He appears to keep Uke‘s hand/wrist attached to his own shoulder throughout the osae.

Toriumi Sensei demonstrates morotedori tenshin taisabaki below:

Toriumi Sensei: morotedori

Beginning tenshin

Enter with ayumiashi

Step back and out with rear leg

With momentum, there is a more pronounced ayumiashi tenkan. See below.

With momentum

Review:

Tori can start at a 0 degree angle…

0 degrees

and end up at 180 degree.

180 degrees

The video:

Endo Sensei demonstrates the shomenuchi shihonage omote initial movement. Special attention is given to his arm movements.

From my understanding, like shomenuchi ikkyo omote Tori‘s forward arm intercepts Uke‘s strike. That arm collapses and hands off the strike to Tori‘s other arm from below. The first arm is free to atemi or continue into the desired technique.

Ai-hanmi shomenuchi

Hand off and about to atemi

Continue with atemi

There are various ways to take Uke‘s balance from yokomenuchi with inside turning. I could not fully appreciate what Tissier Sensei was explaining because my yokomenuchi attacks were not efficient until recently after help from Endo Sensei and Seki Sensei. With the yokomenuchi attack, Uke‘s leg enters first, then his strike with hip twisting. This is the same with Tissier Sensei’s yokomenuchi tenshin taisabaki and kuzushi. See below. Notice how his back leg comes forward and he redirects his energy 90 degrees from incidence, and into Uke perpendicularly.

Tissier Sensei: Redirection

Turn 90 degrees

Either step back:

Step back with rear leg

Or, step forward:

Step forward with rear leg

At the end of his video Aikido Odyssey video he explains this in more detail:1

Here is another similar clip of Tissier Sensei, June 20112

Tissier Sensei shows to not redirect with the front leg. This is strange.

Don't redirect with the front leg

All together with an example (slow motion from [2:24]):

Both in ai-hanmi

Tori does ayumiashi to meet Uke

Tori twists his hips and feet perpendicular to Uke

Tori steps forward into Uke with his rear leg

Additionally, Tori can use a cut down to Uke‘s shoulder/chest as an atemi, or to help the energy redirection. See below.

Additionally, Tori can use a cut-down atemi

As an application, this is effective against a direct or side kick. See below.
