How should I understand mov operations in GNU assembler syntax?

Can someone tell me if my understanding of this code is correct? Move value in memory address in eax to 1st argument i.e 'to_eax' and similar for ebx as well?

__asm__ volatile(                                                       
    "mov %0, %%eax \n\t"                                            
    "mov %1, %%ebx \n\t"                                            
    : : "ri"(to_eax), "ri"(to_ebx) : "eax", "ebx");
