That's not how RF works at all.  The setting of mtry is irrelevant to this.

But shouldn't it be resolved when I set mtry to the maximum number of
variables? 
Then the model explores all the variables for the next step, so it will
still be able to find the better ones? And then in the later steps it could
use the (less important) variables.
