Yup, and the next paragraph:

"If the program dynamically links plug-ins, and they make function calls
to each other and share data structures, we believe they form a single
program, which must be treated as an extension of both the main program
and the plug-ins. This means the plug-ins must be released under the GPL
or a GPL-compatible free software license, and that the terms of the GPL
must be followed when those plug-ins are distributed."
