Usage of set method in LiveLink for MATLAB

I am tying to understand the heat_transient_axi example to export state space matrices to MATLAB from COMSOL. The following lines are from the example
model = mphload('heat_transient_axi');
"Create a parameter T0 that is set as external temperature"
model.param.set('Tinput','1000[degC]');
model.physics('ht').feature('temp1').set('T0',1,'Tinput');
After that there are errors in the example as pointed out here: www.comsol.com/community/forums/general/thread/36587/
Correcting the error the fixed MATLAB code to be run (for the probe mod1.ppb1) is:
M = mphstate(model,'sol1','out',{'Mc' 'MA' 'MB' 'C' 'D' 'x0'},'input','Tinput', 'output', 'mod1.ppb1');
When this model is opened in comsol I can see that 'temp1' refers to a temperature boundary condition imposed on the model and is given by the equation 'T=T0'
So by the line
model.physics('ht').feature('temp1').set('T0',1,'Tinput');
are we setting T0=Tinput=1000[degc]? And what does the 1 do among the arguments for 'set' method ('T0',1,'Tinput')?
And is the input to the system this temperature boundary condition T0?
