I can only give my experience with IS on the 300 F/4 and the 100-400.  I have tried both modes with both lens while shooting birds in flight to try to figure out which is best to use.  From my experience I have found out I don't know which one is better to use.  Taking a panning shot of a bird takes a lot of physical practice - I think Ocho may have been referring to Doodle when talking about an "old dog" about this.  I shot birds with both lens at or about 1600 shutter speed with an F-stop at or around 6.3-8.0, with my ISO on automatic ( which rarely exceeds 400).  The IS mode I use is not a concern for me, if I use one.  Although, have recently been playing with the two modes.  Mode 2 is for panning, but my challenge is taking shots of birds flying across my field of view then they fly in front of me. Does mode 2 affect the quality of the shot when the bird is not flying horizontally?
From my very limited experience with this shooting those eagles, I would say no.  I think "horizontal" is quite a wide option.  Almost none of my eagle photos (in flight) were dead right to left or vice versa.  Most of them were on an angle of some sort or another. Picture facing a clock and starting at the 8 oclock position and finishing at the 2 oclock position on a strafe. That is what I spent a lot of time doing (or just the opposite, depending on where the eagle started his run).
But, if you shoot at those really high shutter speeds, I can see where you might just leave the IS off. I shoot in Av mode and while most of them give me high shutter speeds, sometimes it may occasionally dip below 1000 if the birds are in the tree line. That's why I leave it on.
I am going to try and sneak up this week to shoot more eagles and for the fun of it...I will go with Shutter Priority Mode and see what happens. I wonder if it will take different shots for me or if I will even notice ANY difference?
Take your camera with you dammit. You can't take your next "best photo" if your camera is sitting at home in the bag, now can you?

I wonder if the IS responds to horizontal movement or simply to movement in 1 plane regardless what direction it is?

I think that is the 64,000$ question right there. One would have to take a sh*tload of shots to figure that out completely.
It would be fun to actually see an article where someone went through a bunch of test shots to determine that one way or the other.
