Because it might not load into a server with a lower version.

You cannot do that with the "plain" format, since it writes to a
single file. And you cannot use the "directory" format that would
allow parallelization, because you cannot edit the DDL statements
with a binary format.
Just don't downgrade PostgreSQL. There is no good reason to do that.
