That interpretation of what it should do is wrong. The C99 draft
(which is the only useable reference about // comments in C programs)
clearly demonstrates it in one of its examples in section 6.4.9:

               i();                     // part of a two-line comment

Technically spoken: backslash-newline removal happens before the
source is parsed for comments or any other tokens. This is so even in
old-style ANSI C.

Even if all the snow were burnt, ashes would remain.
