In the errata text it says...

Specify that a missing feFunc[RGBA] acts as a no-op, and for feFunc[RGBA]
specified multiple times the last one is used (check that this is backwards
compatible).

Why choose the last one? Note that for multiple desc/title elements:

If user agents need to choose among multiple
'desc'<http://www.w3.org/TR/SVG11/struct.html#DescElement>or
'title' <http://www.w3.org/TR/SVG11/struct.html#TitleElement> elements for
processing (e.g., to decide which string to use for a tooltip), the user
agent shall choose the first one.

Best regards

Robert
