At an SFG certification, I test all of my students per the written standard. That's how we remove our own little biases from evaluating technique (I like it to look strong and controlled yet graceful and pretty, but that's not in the standard). Not meeting the standard (so not passing) shouldn't depend on the person testing you...you meet it...or you don't.
The standard does state the kettlebell side heel must stay planted during the low sweep and ascend from lunge and the reverse of these two positions. I have seen some small pivots of the toes (often not to torque the knee). The heel stayed planted. But if the heel dances around? A slight bobble on a slippery floor? I'd probably accept. But a slide to accommodate the low sweep cause they didn't have enough space to begin with? Then no, that's not a pass, that's a correction for something that should have been fixed before the transition.
As for the leg popping up from the initial roll to the elbow, that's not pretty, but it's also not in the standard. I personally find that when the weight is relatively heavy for the student, their leg can pop up because their brain is otherwise occupied by a ball of iron above their head. When training their TGU certifying weight, most come in 'owning' that weight and can keep the hip extended for a stronger roll.
On the flip side, training my non-SFG students is still based on our instructor standards - safety first, own each position before you transition, practice where you need to be to express your strength. Within that, there are many options. Turf toe? Plantar flexed foot. Vertigo? TGDowns only. Amputated hand? Sandbag. Post-natal with weak core? Long leg foot against a wall to close the chain. Etc.
