Sixpicker made a good point that it might affect the neck over time to tie it on that way.
In any event, I personally find it more comfortable to have the strap button on the neck heel.
And congrats on your purchase!! A lot of the highest end guitars are using Sitka tops. With the mahogany sides & back it must sound great!
...so ever since then, I always hang on to the buckle.
