No, it's not.

By that argument, the GPL never grants anyone any rights, they always come from the copyright holder. For dual-licensed code, it's the GPL that gives you the right to remove the BSD license notice.

The copyright holder says you may distribute and modify the code under either license. That doesn't let you remove the text of the other license by itself. For example, if both the BSD and the GPL licenses said you could not modify *any* license text, then you still couldn't remove the other license since neither one would give you that right.

However, both the GPL and the BSD license grant the right to modify. Neither requires you to keep any license notices intact except those that refer to that same license.

If you read the GPL carefully, you will see that it requires you to keep intact all notices that refer to *this* license, that is, the GPL. Similary, the BSD license requires you to keep the BSD license notice intact, but not any other licenses.

That is, the original author, by permitting you to obtain the right to modify his work from the GPL, has indirectly granted you the right to remove the BSD license. The GPL grants this right, and the author has permitted you to opt for that license.
