No. He executed a go-around or a "missed approach." That disrupts the whole air traffic around the airport if that happens! If the runway isn't safe to land, then the pilots have to go around and try again. In your case, another plane didn't clear the runway as expected or happened to cross the runway unexpectedly.

It's normal to run the engines to full throttle as the pilots want to get maximum lift (as in they want to get out of there immediately) as the aircraft speed is so low that it's close to stalling.
