String used to convert to and from SQL NULL: When loading data, Snowflake replaces these values in the data load source with SQL NULL. To specify more than one string, enclose the list of strings in parentheses and use commas to separate each value. Note that Snowflake converts all instances of the value to NULL, regardless of the data type.

This function parses text as a JSON document, producing a VARIANT value. If the input is NULL, the output will also be NULL. If the input string is 'null', it is interpreted as a JSON null value, meaning the result is not a SQL NULL, but a valid VARIANT value containing null (the difference is apparent when printing this VARIANT value).

I would expect that tuples where at least one of the members is not NULL, would be included in the count. You can reproduce the behavior with this table: Snowflake maintains statistics on tables and views, and this optimization allows simple queries to run faster. When a row access policy is set on a table or view and the COUNT function is used in a query, Snowflake must scan each row and determine whether the user is allowed to view the row.
