Strontium Nitrate

In a NurdRage video ( https://www.youtube.com/watch?v=_rd8b6wNnKA ) he says once nitric acid and strontium carbonate have reacted leaving Strontium Nitrate in solution that it can just be boiled to dryness as it has a high tolerance for temperature.

However looking at Wikipedia it states:

Melting Point:
570 °C (1,058 °F; 843 K) (anhydrous)
100 °C, decomposes (tetrahydrate)

Does this mean the tetrahydrate decomposes to anhydrous or does it decompose completely and the above video is misleading?

Above 100 degrees it indeed loses water and becomes anhydrous.

Thanks for answering my daft question! I'm quite pleased with the bright red colour it produces with 3:2 mix with sugar.
