SDL_OPENGLBLIT mode

Please tell me is it necessary to use
glEnable(GL_TEXTURE_2D);
void SDL_GL_SwapBuffers(void);
glDisable(GL_TEXTURE_2D);
when I want to flip SDL surface to OPENGL surface ?

Because I can’t
write anything to OPENGL surface. SDL uses 2d texture creation when
user wants to move SDL surface to OPENGL surface, but didn’t use
glEnable,glDisable. Is it wrong ?
