You are correct. It could be the beginning of a line with a right float in 
LTR. So what we really want is to balance the block width taken up by line 
boxes *with* their float shortening taken into account. I’ll have to think 
a bit on how to express that precisely.

I hemmed and hawed a bit about adding another stipulation - lines only 
balance *if* doing so does not change the number of lines. So a single 
paragraph of:

Foo foo foo
foo foo foo
foo foo.

Would not change to:

Foo foo
foo foo
foo foo
foo foo.

Even though that gets you the best balancing result. For headlines and 
captions, I think this is what’s usually intended (balance the lines, but 
not if that makes an additional line). But I’ve heard some pushback on 
this idea.
