1km swim is probably not a lot.
But I think that doing a swim directly after a weigh session would be savage.
In that the training would be more metabolic rather than draining.
I think putting on mass is the least of his problems right now.I used to find it impossible to put weight on when I was doing karate...
3 hour sessions 3 x a week and by the end your gi is drenched in sweat.
I reckon you'll know for sure after a while of doing it if it is hindering any gains you are trying to make in mass/weight.
If you're happy with the current routine, keep at it

Yeap.
150 kilo's is quite enough at the moment!
As for weight lifting/strength gain, it seems to be coming along pretty good.
