So if I do M-NUMBER, "P" should send nothing.

No. When you execute a command there is only one prefix argument but
Emacs knows two different _representations_ of it. So, when you type
C-u M-x command RET
the "command" gets a prefix argument. Its representation in "raw" format
is "(4)", that is, a list with a single item, the integer 4. Its
representation in "numeric" format is the integer 4.
