Are these two "Code Snippets"?

Question

people use "Code Snippet" or "Code Snippets" everywhere.

"Code Snippet" is a term used to describe a small portion of re-usable source code, machine code, or text.

following lines of code comes from wiki (denote as snippet_1)

temp = x
x = y
y = temp

and another (denote as snippet_1)

Hello {%first_name%} {%last_name%}

it seems that "Code Snippet" is a countable noun. so, snippet_1 and snippet_2 are two "Code Snippets"?

do I use this term correctly?
