How do I split a surface, with the result of a face blend?

I'm trying to better my surface modelling, and so I thought I'd recreate the model that was shown in Cody Armstrongs demo project (https://youtu.be/GZJjMLeOkU4?si=FEayL4XqlT89i_XU&t=1652), around 27:32.
Right now the right hand edge of the boundary surface extends above the top right red circled vertex. Before I do my first boundary surface (red arrows are my intention), I figure I need to cut the RHS one so that the blend has the right edges to work with.
I was able to cut the left of the two, but I cannot cut the right. I get 'selected entities do not split selected faces'.
I'm not sure if I've done something wrong, or am just going about this the wrong way.
I'm also only guessing that this is what was done in Cody's project.

Any suggestions?

There is no intersection at your upper right circle. The edge of the light blue surface and the corners of the dark blue surface would need to intersect.
Its not as bad as my pic makes it. I had high quality turned off. but its still not perfect because you used a different method to attack that edge vs the left side.
Do you mean this vertex?
and if so, given that's from a face blend (and so my understanding is that it should perfectly intersect the target face), how should I approach a fix, and what might that fix be?
My apologies. it actually the opposite corner. that's giving you grief. have the bridging curve 2 defined by the face edge and not the fillet edge and you can boundary fill.
it does seem odd that when split 1 occurs it pushes the edge of the fillet out past its original position. that might be a question for support.
nevermind. it doesn't to that. this is a snapshot before the split occurs. grey is face blend and blue is boundary surface. for whatever reason the face blend is not following the boundary surface good enough. That's a question to be answered by someone with far greater experience than me.
Thanks for the ideas. I changed 'some things' and now it works, but I couldn't tell you why. I feel liek I've clicked/modified the features 1000 times trying to get this to work. Now I can cut the other faces using the face edges. and if I can't, I've found creating a compound curve from the curve I want to use seems to work. …
Thanks again.
Awesome. Congrats. Learning the surfacing tools can be challenging but can definitely add a real nice niche to your skill set.
