OK, I get it!

Did you read this

  Only single-character comment start and end sequences are represented thus.
  Two-character sequences are represented as described below.
  The second character of NEWENTRY is the matching parenthesis,
  used only if the first character is ‘(’ or ‘)’.
  Any additional characters are flags.
  Defined flags are the characters 1, 2, 3, 4, b, p, and n.
  1 means CHAR is the start of a two-char comment start sequence.
  2 means CHAR is the second character of such a sequence.
  3 means CHAR is the start of a two-char comment end sequence.
  4 means CHAR is the second character of such a sequence.

in `modify-syntax-entry'?

Weird/bad this isn't already in the mode BTW ...
