Furnace Blower Question ....Is This Normal

I have a Rheem 90 Classic Plus Furnace Two Stage. Once i Raise temperature (for Heating), i hear the fan kick in, burners ignite, then fan/blower goes into high speed for about 10 minutes, then goes back to a low speed even if it hasn't reached desired temp. Is it normal that high speed is only on for 10 mins?

Also to feel the heat in low speed i gotta put my have real close the the vent, barely coming out.

How much are you increasing the setting on the thermostat? Do you know if you have a 2 stage thermostat? If the room temperature comes up to within 1-2 degrees of the setting within that 10 minutes, I would say the operation is normal.
