I thought that might be the case, but the man page says:

# Commands are executed by cron(8) when the minute, hour, and month of
# year fields match the current time, and when at least one of the two
# day fields (day of month, or day of week) matches the current time
# (see ``Note'' below).

...

# Note: The day of a command's execution can be specified by two fields
# -- day of month, and day of week.  If both fields are restricted (ie,
# aren't *), the command will be run when either field matches the
# current time.  For example, ``30 4 1,15 * 5'' would cause a command
# to be run at 4:30 am on the 1st and 15th of each month, plus every
# Friday.
