I've seen that video -annoyingly they don't expand on why they say it's the front Left wheel.
Interestingly, Haynes says bleed order for RHD cars is:
RH Front
LH Front
RH Rear
LH Rear
For LHD cars they just flip the order L to R
Normally I would have started with the furthest away wheel -taking into account the Master cylinder and ABS pump location - so Rear Right.
