Here's an example I found online. I wasn't familiar with the term either. We used to do something very similar as part of our tsuki kotegaeshi standard, but have since changed it up a little.
I remember thinking it didn't seem very realistic for my skill level, but I always liked it as a connection exercise. Somewhat ironically, I did think shomen uchi was more realistic, but this doesn't seem much different than that, but tilted to the side more.
My guess is that, ideally, combinations shouldn't be possible since ideally control is attained at the moment of first contact, but I can see how it might be a good way to slip into the rear corner, making the follow up attack less optimal. All that said, hopefully in the long time it took me to post this short non-answer someone with real experience has replied.
Take care,
Matt
