Language is most definitely a thing of flow.
I had my English book open, the Japanese pdf on screen, and the audio on the go. I was juggling all three, going nicely. But after a spell, I suddenly got the inclination to do a little less ‘glossing’. I wanted to examine the text more closely.
Could I read a sentence in one language, then the other, and finally finish off with a listen?
In theory, that sounded good. But in practice the idea fell down. Breaking the story up into sentences proved to be just too much of an interruption.
