Section 4.6. "match Statements" of the Python 3.10 tutorial says:

"""
You can combine several literals in a single pattern using | (“or”):
"""

For someone just learning Python, this may suggest that | is always "or", when in fact it is a bitwise operator (that may be overloaded), but inside a match clause has this special meaning without any overloading. 

I believe this exception should be made explicit in section 4.6, otherwise it may lead readers of the tutorial to a misconception.

This seems fine to me.   In pattern matching, it has both the meaning and pronunciation of "or":

    case "this" | "that": ...

It has similar mean in the re module:

    r'abc|def'

And it is also used the same way in typing:

   s: list | tuple

We've also long used it for sets:

   rich | tall       # People who are either rich OR tall  

Based on this, I don't there is any reason to suspect it will be confused with bitwise-or.

The only place the operator really isn't harmonious is with dicts where its meaning is "update" and where it isn't commutative.

Another other thought, PEP 634 defines "|" as being an "or-pattern", so it part of the spec:
