Confusion about Bottom of Stack in MPLS header

Sir, I want to bring your attention toward a specific field in MPLS header , is Bottom of stack

you have mentioned in the video as well as in the notes that bit 0 indicates that this is last label and 1 does that there are more labels on stack

But what I found from other sources is just opposite that 0 means there are more labels in stack and 1 means this is last label

May be I am wrong , So please let me know if I am.
