emacs -Q
In *scratch*, type a backslash followed by a TAB and a letter:
\ b
Put the cursor on the letter.
M-: (skip-syntax-backward "\\s-")
The cursor is on the backslash. IOW, it skipped not only the
whitespace but also the \, which should have escape syntax.
This is the first time I've noticed this, so I'm guessing there is a
good explanation and this behavior is somehow correct. But looking at
the Elisp manual, I don't get that impression. Willing to learn...

The SYNTAX argument to skip-syntax-forward and -backward is not a
regexp.
The argument in the example above means to skip any character with any
of 3 syntax classes:
\ escape
s [not a valid syntax class]
- whitespace

Yes, someone else already pointed that out.
Thanks.
