Because its the same reaction.

Explanation:

A monobasic [monoprotic] acid like HCl has one H atom, which fully dissociates to form a hydrogen ion, #H^+#. The strong alkali fully dissociates to forman hydroxide ion #OH^-#, which react to from water. This is the ionic equation for neutralisation and occurs for all strong acid/strong alkali reactions.
