If this is true for MSC 5.0, they fixed it in MSC 5.1.
From MSC 5.1 Language Reference, Section 5.3.11, p. 130:

5.3.11 Sequential-Evaluation Operator

The sequential-evaluation operator evaluates its two operands sequentially
from left to right. ... The sequential-evaluation operator, also called
the "comma operator," is typically used to evaluate two or more expressions
in contexts where only one expression is allowed.
