No. Prerequisites to .INTERMEDIATE _MUST_ be plain filenames, not
patterns.

This rule doesn't do what you think it does. Pattern rules require all
targets to contain a '%' (pattern specifier).
Basically, this is treating index.html as a separate target that depends
on the literal file name '%.tex'. Your makefile never tries to build
index.html. Because make never thinks that this file is built, it never
tries to delete it.
In fact, I think this is a bug in GNU make: you should either get an
error here, or all three targets should be treated as explicit targets.
If you move the index.html file so it's not first in the list, for
example you'll get an error:
Makefile:5: *** mixed implicit and normal rules. Stop.
