Because 0xA9 is invalid sequence in 7-bit encoding. I have tried two randomly
chosen XML parser and both choke on this example:

$ cat test.xml
<?xml version="1.0" encoding="us-ascii"?>

$ xmllint --noout test.xml 
I/O error : encoder error
test.xml:2: parser error : Premature end of data in tag test line 2

$ xjparse test.xml
Attempting validating, namespace-aware parse
com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Byte
"169" is not a member of the (7-bit) ASCII character set.

So in my opinion Encoding spec breaks compatibility with existing content and
implementations in regard to "us-ascii" encoding.
