Dmitry, 

"Check" and "Verify" have slightly different meanings.

"Verify" implies that your statement has an assumption, which in this case is " Savanna can create template". "Check" makes no assumptions about what you're looking at and doesn't assume any result. 
If you have the exact same construction in all Sanity Tests, you can leave this for now. However, we will need to change this in the future. 

A good example:
