We can now dissect the arguments used on the 5H bid discussed:

The 5H bid conveys the information of some strength in Hearts and this
meaning is within one of the descriptions for the call not being
conventional. (Whether this information is positive information or inference
is at this stage immaterial.)

The 5H bid also conveys the (positive) information that the player holds a
particular card, i.e. the Ace in Hearts, and this meaning is not within any
of the three descriptions for a call not being conventional. 

I take Grattan's last statement to the effect that this last meaning of the
5H bid makes that call conventional, an interpretation with which I in case
fully agree.
