It's probably simpler than a cortisol release. If you're at rest or under slight but steady load, there will likely be a general balance between bg and ifg.
Then, if you start carting a dog up upstairs, heart rate likely goes up, the extra pressure from the faster heart rate will increase pressure in capillaries, so they'll leak more glucose out into the lower pressure interstitial fluid, which is a good thing as the muscle cells the if serves needs more glucose for carrying the pet, so libre senses the higher glucose there and reports it. Then when heart rate goes down, it balances out again.
When I first started using libre, I didn't appreciate the interplay between the two spaces - blood and interstitial fluid - and it took me a while to understand the relationship between them, the way that glucose naturally seeps out of blood into if to deliver to cells, and will do so more when heart rate goes up.
Thank you Scott, that explains everything. I will be more careful tomorrow.
